This library has been written to generate a SVG image of QR Code in Node.js, goals:
Install the package:
List of options:
Container options:
Output with rect elements
Responsive web page
Squares joined into one path shape produce a compact file size, i.e. 4-5x reduced compared with rect elements. A single path element will result in an optimized rendering, thus not producing any minor gaps between the squares. Also using the container with viewBox attribute may contribute to the responsive scaling on the web.
Set join to true
Output with path element
Algorithm defines the square pattern once before populating a canvas. Useful if you want to generate QR Code with candies. However, some SVG software and converters do not support defs or use elements.
Set predefined to true
Output with defs and use elements
Convert to other formats
Using html-pdf to convert SVG to PDF (or PNG or JPEG)
Qr code generator
To generate a QR code select the type of barcode you would like to create, enter the data to store and hit the green button.
What is this tool?
It is a free QR code generator tool that allows you to create QRcodes for a variety of different purposes.
The first option is a URL, this could be a link to your website or app on the App Store. When a person scans your Qr code they will be given the option to visit the given link. Remember to use itms:// instead of https:// in order to go to the App Store.
Vcards are used to automatically add contacts on your phone. This Vcard QR code generator has a bunch of the most common information you will most likely want to store such as name and number. A great case use for this would be on business cards.
The text option is the most basic. When users scan the QR code they are presented with whatever message is contained within it. Simple, but there could be many uses for this.
Email is to allow the user to automatically open up a new message with your email address and a subject already added. If you would like the user to be sending mail to multiple email addresses simply add one after the other separated by commas e.g. [email protected], [email protected]
SMS opens up a new text message with your number and the message they should be sending. There are many great uses for this, especially things such as donating to charity, where the user has to send a specific message in order to donate. It removes some of the hassle and human error, making a QR code an essential asset in whatever campaign you are running.
This tool provides three ways of using your newly generated QR code. The first is to download a png image to save for future use. Secondly, using a tag containing a base64 encoded version of the image to directly onto your website. Thirdly using the SVG code, which can be put directly into your HTML or imported into popular editing software such as Photoshop or Illustrator.

Создавайте, сканируйте и подключайтесь! Нет ничего проще! Если вы спешите, QR-код будет сгенерирован, как только вы введете данные в приложение.
Это, безусловно, самый простой и удобный способ подключиться к сети Wi-Fi без ошибок в написании.
Вы можете сгенерировать все QR-коды для подключения к нужной сети Wi-Fi.
Зачем использовать генератор QR-кода?
Раньше нужно было выбрать сеть Wi-Fi из списка доступных сетей и ввести пароль вручную. Теперь наш генератор позволяет вам создать QR-код, который сделает все за вас. Как? Просто наведя камеру телефона на код или используя считыватель QR-кода. Самое приятное то, что наш WiFi QR-код полностью бесплатен, а созданный код никогда не истечет (если настройки вашего маршрутизатора не были изменены). С помощью QR-кода WiFi вы можете поделиться сетью Wi-Fi с друзьями, семьей и даже клиентами. Откройте для себя потенциал и преимущества совместного использования Интернета с помощью QR-кода.
Моя сеть Wi-Fi скрыта, могу ли я создать QR-код?
Конечно. Просто нажмите «скрыть» рядом с полем «Имя сети» в нашем генераторе QR-кода WiFi. Если ваша сеть Wi-Fi не скрыта, но вы хотите включить эту опцию, обратитесь к руководству вашего маршрутизатора или руководству о том, как скрыть вашу сеть от современных маршрутизаторов.
Какой протокол безопасности мне нужен для моего Wi-Fi? WPA / WPA2, WEP или нет?
Создавайте QR-коды для подключения к WIFI в вашем доме или на работе, не сообщая никому пароль, делитесь QR-кодом со своими коллегами, друзьями или людьми. Теперь вы можете наслаждаться темным режимом и, следовательно, генерировать QR-коды WIFI с меньшим расходом заряда батареи.
Помните, что вы можете сгенерировать QR WIFI из любой сети, если у вас есть данные из нее, для них безопаснее подключаться с помощью QR WIFI, чем давать им лист бумаги с паролями или диктовать их, если вам нужно дать ваши данные для любых людей это ваше приложение для генерации QR для Wi-Fi.
Контролируйте, кто подключается к вашему Wi-Fi, создавая необходимые QR-коды и передавая их всем, кто принадлежит, что повышает безопасность вашей сети Wi-Fi.
Мы рекомендуем использовать функцию совместного использования генератора QR-кодов Wi-Fi, поскольку таким образом вы можете напрямую поделиться QR-изображением своей сети, и люди могут безопасно и легко подключаться с помощью вашего QR-кода Wi-Fi.

Frequently Asked Questions
What is a QR code and why do I need one?
A QR code stands for ‘Quick Response Code’ and is a 2-dimensional barcode type invented by Denso Wave in 1994. You can get more information at Wikipedia. Today QR codes are used a lot to give a digital dimension to a product or flyer that leads to a URL.
What is the difference between a static and dynamic QR code?
With a dynamic QR code you can track data and you can edit your content at any time to a new content with the same category, this saves you time and money on printing. With a static QR the user will go direct to your embedded data i.e. URL and text, however data cannot be tracked and you are unable to edit your URL. For marketing, Dynamic QR codes are more useful as you can track the following pertinent scan statistics: the number of scans, the time when the user scanned, the location of the scan (city/country) and the device type of the user (iPhone/Android).
Can I switch from a static to a dynamic QR code?
No, once you select and make a static QR we cannot change it to a Dynamic QR code. Static and dynamic QR codes are two different QR code types.

You can scan your dynamic QR codes as many times as you like until your paid subscription expires.
Can I delete a dynamic QR code?
Yes, if you use it for less than 8 scans you can still delete it on the track data page.
My QR code is not working, what can I do?
There are many reasons why a QR code is not working correctly. First check your entered data. Sometimes there are little typos in your URL that break your QR code. Make sure that there is enough contrast between the background and foreground of the QR code. The foreground should always be darker than the background.
Can I save QR codes as a template and can I delete a template?

QR Code Sizing : To ensure that people can automatically scan your QR code with just one try, always take a look the size of your QR code you are displaying.

Выбираем генератор QR-кодов — обзор 15 лучших сервисов
Генератор QR кода онлайн QR Stuff
Этот генератор QR-кодов позволяет конвертировать в QR-код несколько типов данных — URL-адреса, видео YouTube, местоположение на Google Maps, профили Facebook, LinkedIn, Instagram, Twitter, ссылки «Купить сейчас» через PayPal, текст, sms, звонки, геолокацию, события, адреса электронной почты, Wi-Fi.
Также существует дополнительная опция, позволяющая изменить цвет QR-кода:
Как теперь восстановить пароль, доступ к странице?
Восстановить по электронной почте
Если у тебя подключено дополнительное подтверждение входа, то вместо быстрого восстановления пароля по СМС применяется восстановление пароля по e-mail (электронной почте). Привязана ли твоя страница к электронной почте? Если да, то можно запросить на нее ссылку для восстановления пароля (инструкция откроется в новом окне).
Может оказаться, что страница к почте привязана, но войти в почту ты не можешь (нет доступа или просто ее не помнишь) — в этом случае лучше попытаться сначала восстановить доступ к почте, иначе у тебя останется единственный способ, он более сложный и требующий намного больше времени. Читай дальше:
Восстановить через службу поддержки
Других способов восстановить доступ нет. Искать их бесполезно. То есть по-другому вообще никак не восстановить. Ты только что прочитал все возможные способы. Прочитай их еще раз, если не понял.

Если вы пользуетесь компьютером или ноутбуком и предпочитаете установить для этих целей программу, то могу порекомендовать утилиту — QR-Code Studio. Она довольно простая в использовании и обладает приличным функционалом.
Адрес: QR-Code Studio
Программа работает очень быстро и имеет множество настроек в создании QR. Она бесплатная для частного использования и полностью на русском языке.
Особенности:
Интересно! Вообще программы не так популярны для создания QR. Поэтому их не так много можно найти в интернете. Лучшим решением все-таки является использование сайтов или приложений для смартфона.

Программы для создания QR-кодов
QR-код представляет собой матричный код, который в настоящее время особенно актуален для считывания через камеры мобильных устройств. Технология активно применяется в маркетинговых целях, преимущественно для продвижения своей компании и продукции в частности, однако это далеко не единственная информация, которую можно уместить в QR-код. Не менее востребован перевод таких данных, как физический/электронный адрес, визитка, номер телефона. Преимущества QR-кода перед обычной напечатанной информацией очевидны: в них можно уместить гораздо больше зашифрованных символов, а пользователю не нужно набирать буквы, цифры и символы вручную, чтобы сохранить какие-то контакты, перейти на веб-сайт, достаточно просто поднести камеру приложения, распознающего этот вид штрихкода, как сразу же произойдет считывание с дальнейшей обработкой полученных сведений. Чтобы работать с двумерными кодами на постоянной основе и иметь возможность придать им индивидуальности, пользователю необходимо воспользоваться специальным ПО. Именно об этом и пойдет речь далее.
QR Code Desktop Reader & Generator
Начнем с простого представителя этой категории софта, который умеет не только создавать, но и считывать коды. Его функциональность максимально незамысловатая, поэтому всем тем, кто не желает тратить время на редактирование будущего штрихкода, настраивая прозрачность, цвета и прочие параметры, следует обратить внимание именно на данную программу. Как таковых возможностей создания QR-кода здесь практически нет: вписываете текст, настраиваете разрешение и сохраняете полученный результат в JPEG либо PNG.
Программа бесплатна, русский язык отсутствует, впрочем, при работе здесь он практически и не нужен. Если планируете часто или время от времени создавать простейшие QR-коды, а также, вероятно, считывать их, не желая пользоваться онлайн-сервисами, это ПО — подходящий выбор. Ее небольшой размер (менее 10 МБ) не скажется на занятности дискового пространства, а простейший интерфейс не заставит осваивать принципы работы.
QR-Code Studio
Второй в нашем списке будет программа, название которой также говорит само за себя. Здесь каждому юзеру предлагается детально настроить двумерный штрихкод, регулируя доступные параметры. Вся работа происходит в одном лишь окне, имеющем пару вкладок и вертикальную панель инструментов. Несмотря на простой интерфейс, тут присутствуют практически все необходимые свойства, которые позволяют создать QR-код желаемого уровня сложности. Первым делом понадобится ввести текст, который в дальнейшем будет преобразован. Чтобы в этом вопросе не возникло никаких трудностей, софт предлагает воспользоваться помощником ввода данных — это будет особенно актуально и полезно новичкам или всем тем, кто пытается закодировать нестандартную информацию.
После выполнения основных действий остается настроить технические параметры: единицу измерения, размеры, разрешение, размеры символов и др. Приложение поддерживает сразу несколько кодировок: UTF-8, Latin-1, китайскую и японскую. Чтобы красиво оформить свой QR-код и привлечь к нему больше внимания, позволяется настроить цвета и прозрачность. Цветным можно сделать изображение, фон, текст. Когда, наоборот, необходимо уменьшить вес будущего кода, лучше задать прозрачный стиль фона и сохранить его как PNG-файл. Особые дизайнерские решения через эту программу реализовать, понятное дело, не получится, однако сделать классический или более интересный вариант 2D-кода за короткий промежуток времени вполне возможно. В программе имеется русскоязычный интерфейс, а распространяется она бесплатно для Windows и Mac OS.
QR Customizer Pro
Более продвинутое решение представляет собой эта программа: с помощью нее вы сможете создавать QR-коды любой сложности в кодировке UTF-8. Здесь есть сразу несколько шаблонов: каждый из них предназначен для определенных целей и на основе выбранного будет реализовываться основная задумка. Так, здесь можно выбрать:
Конечно же, тут присутствует функция визуальной персонализации создаваемого элемента. Помимо разработки стандартных черно-белых вариаций, юзер может добавить немного индивидуальности, поместив на задний фон, например, логотип своей компании или просто сделав весь квадрат цветным, воплотив собственные задумки. Поддерживается создание и прозрачных QR-кодов, которые будут сливаться с фоновым изображением или дизайном сайта/этикетки, привлекая к себе еще больше внимания со стороны аудитории, но при этом продолжая оставаться такими же функциональными, как и обыкновенные варианты. Для придания максимальной уникальности воспользуйтесь инструментами рисования (заливка, кисть, ластик), а также инструментами для изменения цветового оформления, вставки логотипа, тени, 3D-эффектов, рамок. Чтобы QR-код получился максимально качественным, здесь есть сразу 4 уровня исправления ошибок. При всей своей функциональности программа не требовательна к ПК, имеет бесплатную ограниченную версию лишь с основными функциями. Для создания уникальных QR-кодов придется приобрести Pro-версию, однако даже там отсутствует русский язык интерфейса.
Free QR Creator
В противовес предыдущей программе рассмотрим Free QR Creator. Еще одно крайне простое решение, не требующее от пользования никаких технических навыков для генерирования. Умеет создавать обычные и микро QR-коды. Весь интерфейс состоит из одного окна со строкой меню. Позволяется создать обычный черно-белый вариант или раскрасить передний и задний план, повернуть квадрат, добавить границы. Разделения на категории для текста отсутствуют, есть лишь обычная строка и пара инструментов редактирования внешнего вида. Все изменения отображаются в live-режиме через окошко с превью.
Результат доступен для сохранения в один из следующих форматов: BMP, JPG, PNG, GIF, TIFF и EMF. Программа полностью бесплатна, занимает 5 МБ на жестком диске (есть и portable-версия), не имеет перевода на русский язык, но даже базовых знаний английского хватит для полноценного взаимодействия.
My QR Code Generator
Следующей в списке идет программа чуть функциональнее предыдущей. Если прошлый софт (как и первый) имел всего лишь одно поле для ввода любого текста, тут же процесс более оптимизирован под разные направления. Можно создать персонализированный QR-код с URL, обычным текстом, SMS, номером телефона, визитной картой, E-Mail, Wi-Fi, платежной системой. Все описания этих разделов вы найдете в кратком обзоре QR Customizer Pro чуть выше.
Получившееся изображение может быть масштабировано на усмотрение пользователя до 500 пикселей. Раскрашивать и как-либо «украшать» получившийся QR-код не получится, результат можно только сохранить или скопировать в буфер обмена. Очень легкий софт, имеет портативную версию, перевод на русский язык отсутствует, как и везде. Пригодится лишь только для быстрого создания штрихкода какой-либо категории.
Free QR Code Generator
Теперь вкратце рассмотрим программу Free QR Code Generator, представляющую собой смесь двух предыдущих. Пользователь может выбрать, для каких целей будет создаваться будущий QR-код, указав одно из направлений: текст, ссылка, телефон, электронная почта, контакт, СМС, геометка. Определившись с типом информации, остается ввести нужную информацию, которая будет кодироваться. Далее можно либо сгенерировать классический двумерный код, либо слегка видоизменить его внешне. Вспомогательных инструментов здесь почти нет, поэтому сделать более красивым штрихкод не удастся. Тем не менее тут присутствует выбор размера пикселя, регулировка прозрачности, выбор уровня проверки на ошибки и указание формата изображения, например, PNG.
Вносимые изменения можно просматривать сразу же в окне с превью. Как понятно из названия, софт полностью бесплатен. Он довольно легкий, без перевода на русский язык, который, впрочем, здесь и не нужен, так как параметров никаких практически и нет. Загрузить Free QR Code Generator на свой компьютер можно с официального сайта разработчика по ссылке ниже.
Labeljoy
Многофункциональное ПО в стиле офисных приложений от Microsoft, позволяющее создавать различного вида штриходы, в том числе и двумерные. Пользователю предлагается выбрать тип кодировки, размер символа, уровень коррекции ошибок и оптимизацию под конкретные устройства и форматы. Дополнительно можно настроить шрифт, воспользоваться инструментом «Перо», задать фоновое изображение и некоторые дополнительные параметры. Благодаря всему этому появляется возможность персонализировать QR-код под какой-то определенный тип информации. Результат может быть экспортирован в формате PDF, JPG, PDF.
Так как ПО нацелено в первую очередь на бизнес-использование, тут имеются функции соответствующего направления: импорт информации, из которой будет состоять текст, из базы данных, печать этикеток. Здесь легко задавать нужные поля без необходимости их ввода вручную, имеется инкрементальный счетчик. Демо-версия имеет водяной знак и другие ограничения, кроме этого можно купить одну из трех версий и получить доступ к созданию самых разнообразных видов штрихкодов, а не только QR. Labeljoy — одна из немногих программ этого рода, где присутствует перевод интерфейса на русский язык.
Barcode Maker
Заключительной стала программа от Aurora3D, позволяющая создавать штриходы разных форматов. Среди них есть и интересующие вас QR/micro QR. Сперва следует выбрать подходящий шаблон, а затем приступать к созданию. Тут нет выбора типа информации, которую будет содержать в себе QR-код, но имеются другие варианты настроек, по большей степени касающиеся внешнего вида. Можно менять цвет переднего и заднего фона, размеры. Софт полностью поддерживает Unicode (латинские, арабские, японские, китайские, корейские символы), возможна пакетная генерация. Для последнего необходимо предварительно задать правила или импортировать нужный текст.
Файл сохраняется в различные форматы: PNG, JPG, BMP, SVG, TIFF, SVG, EPS. Софт русифицирован, у него есть демо-версия, но чтобы пользоваться всеми функциями на постоянной основе, понадобится приобрести лицензию. Скачать или купить Barcode Maker можно на официальном сайте, кликнув по ссылке ниже.
Мы рассмотрели несколько основных программ, имеющих разный уровень сложности и функциональности. Одни подойдут для быстрого и незамысловатого создания, а другие — для профессиональных целей, которые можно использовать на своих веб-сайтах и этикетках продукции. Ко всему прочему предлагаем ознакомиться с нашим материалом по онлайн-созданию QR-кодов, используя различные браузерные редакторы.

Почему быстрое восстановление пароля у меня недоступно?
Как войти на сайт ВКонтакте, если забыл пароль и включена защита входа (подтверждение входа)? Ты пытаешься восстановить доступ, но получаешь сообщение об ошибке:
Быстрое восстановление пароля недоступно. Для вашей страницы включено подтверждение входа по мобильному телефону.
К сожалению, вы не можете восстановить пароль по указанному номеру телефона.
Это значит, что когда-то раньше ты сам включил подтверждение входа по мобильному телефону, когда для входа на страницу надо ввести не только пароль, но еще и код, присланный на телефон.
Конечно, это повышает безопасность и защищает от взлома, но теперь ты забыл пароль. Что делать? Получить код восстановления на телефон теперь никак нельзя, потому что подтверждение входа
— это когда ты и знаешь пароль, и имеешь доступ к телефону. И то, и другое вместе. Только так обеспечивается безопасность, которую ты сам добровольно включил. Уже нельзя восстановить страницу с одним только телефоном, если не знаешь пароль.

Для чего добавлять лого в QR?
Выбрав в качестве изображения для кода логотип вы привяжете код к компании и визуально и информационно, привлекая большее количество клиентов.
Используйте четкий логотип без размытостей, помещая его в центр кода. Так можно избежать препятствий для чтения элементов самого кода. Лого должно дополнять код, и не мешать его сканированию.

QR code SVG format: Resize your QR codes to any sizes
If you’re planning to resize your QR code as larger as you need it to be, then downloading and printing your QR code in SVG format is your best option.
QR codes in SVG (Scalable Vector Graphics) format enables you to adjust your QR code into different sizes without affecting the image’s original quality.
However, not all QR code generators give you an option to download your QR code SVG format.
Using QRTIGER can generate your QR code, download, and print it in SVG format. Here’s how you can do it.

How to create a QR code in SVG format? A step-by-step guide
Go to www.qrcode-tiger
QRTIGER allows you to customize your QR code and download it in SVG format.
Click the type of QR code solution you need
There are multiple QR code types or solutions you can generate for your need. Choose from the options in the box shown above.
Select dynamic instead of static
As we have discussed, there are two types of QR codes you can generate. It’s either you choose to generate it in static or dynamic QR code.
However, with dynamic QR codes, you can set-up a QR code tracking system and trace your QR code scans and edit your QR code to another information or landing page if necessary.
You can do this even if your QR has been printed.
Personalize your QR code
You can also make a creative QR code design and personalize your QR code in SVG formats such as adding a logo, image, icon in your QR code.
You can also choose the layout patterns for your QR code, set the colors, add a customizable frame with a call to action, and more!
Do a scan test
Before your download your QR code, it is always best to do a scan test first if your QR code reads and redirects you to the correct information you have encrypted.
Click «download SVG»
Download your QR code in SVG format and resize it according to your wants and needs.
Print and distribute
After you have done a scan test, you are now ready to print and distribute your QR code.
Use cases of QR codes in SVG format
Billboards and Posters
One of the most notable uses of a billboard QR code is when the marketing campaign of Calvin Klein surfaces in the public streets.
A huge billboard QR code with the name of their brand attached to it with a very suggestive call-to-action «Get it uncensored» where people can scan it from afar.
Window store
Zara, one of the most popular fashion and apparel brands, has taken its marketing initiative to the next level.
They put a QR code in their window store that allows the passer-by to scan the QR code that will lead them to shop online for their brand.
Delivery Boxes/ Product boxes
Printing a larger QR code size for your delivery boxes is better so that your recipient will notice the QR code. You can generate a QR code that will lead them to the product details!
Vehicles
QR code on marketing vehicles has also become a common sight used by marketers. Usually, this QR code on vehicles leads the scanners to the contact information of the marketing company.
T-shirt
Viral QR code t-shirt design for the QR Code Campaign in Boulder, Co, for the band SoundRabbit, was designed and printed on t-shirts to allow scanners to download free music.
They incorporated a custom stylized windmill vector graphic to tie into the song topic, wherein they made a slightly larger QR code size and printed it on t-shirts.
The basics of QR code
Any QR code solution you create can either be generated in static or dynamic QR code. So what are these, and what is the difference between the two?
Static QR code
Once you generate your QR code in static mode, you cannot modify or change your QR code’s content, and you cannot track your QR code scans.
Dynamic QR code
When you generate your QR code solution in a dynamic model, you can change your QR code’s content to another landing even when your QR code has been printed.
Dynamic QR code is the best option to choose if you want to save money in the long run.
Best practices when you create your QR code in SVG format
Do not mix light colors.
The background of your QR code should always be lighter than the foreground color. QR code scanners are set to scan QR codes with a darker foreground and a lighter background color.
Also, avoid colors such as pastel and yellow colors and create enough contrast of your QR code colors.
Sizing matters
QR code size matters. Before you print and distribute your QR code, always make sure that you have printed it the right size according to its advertising environment.
The recommended QR code dimension is 32 x 32 millimeter but you can also resize it in your SVG format that will be scannable depending on your QR’s advertising environment.
Put a customizable frame with a call to action in your QR code.
Your QR code won’t serve any purpose if your scanners don’t do what to do with your QR code. Thus, it is crucial to put a call to action in your QR code like «Scan Me» or «Scan to watch a video!»
Make your landing page mobile-friendly
Your scans will most likely get from smartphone gadgets, making your landing page mobile-friendly and easy to load.
Only implement the action you are promoting in your QR codes.
When implementing QR codes, one common mistake marketers make is that they tend to over-analyze and complicate their QR code campaign.
One of the rules that need to be understood is that make your landing page concise and simple.
If your landing page leads scanners to a video, then put a call to action that says «scan to watch a video» and nothing else. Do not create confusion among your scanners with unnecessary add-ons.
QR code SVG format: The perfect option when it comes to resizing your QR codes
Resizing your QR code does not merely limit the above-mentioned use-cases. You can resize your QR code even if you only attached them to a magazine, a flyer, or in your business card or vCard QR code.
The bigger the view, the better. However, the further you will place your QR code, especially if you want the public to scan it, the bigger the size should be for good visibility and better scan.

How to make a QR Code generator using JavaScript?
While you can generate QR codes for URLs in browsers such as Chrome, it’s always interesting to learn how you can make your own version of a simple QR code generator. So, here we go.
Here’s a quick look at the HTML code and it’s pretty straightforward.
Exit fullscreen mode
The last element is for the QR code to be displayed as soon as we fetch it from a library through javascript (more on that later).
Let’s move on to some javascript.
JavaScript
First of all, we will create an event for when the user clicks on the Generate QR code button.
Exit fullscreen mode
Now, we are going to create a function known as generate() which will be invoked as soon as the user clicks on the Generate QR code button. This function will take the text input from the user as a parameter.
Exit fullscreen mode
Inside this function, we are going to use a javascript library qrcode.js to generate QR code. You can use this library via a CDN by including the below
Exit fullscreen mode
Inside the generate() function, we will create a new object using the given library. It will take two arguments, first is the element in which the QR code has to be displayed and secondly, the content for which the QR code has to be generated and some options to customize the QR code.
Exit fullscreen mode
Next, we will create a download button and append it below the QR code.
Exit fullscreen mode
Inside this download button we will add a link which allows users to download the QR code with a specified file name and append it into the download button. You can learn more about the download attribute here.
Exit fullscreen mode
Let’s figure out the href attribute of the tag next.
The qrcode object will return a canvas element as well as an image element.
In the case of desktop, it’s pretty obvious. We just have to grab the value of src attribute of the image element and assign it to the href attribute of the download link ( tag) after a specified amount of time (0.3 seconds) using setTimeout() function because the QR code takes some time to be generated.
Exit fullscreen mode
But how do we get the dataURL from the canvas element? By using the method toDataURL() on the canvas element.
Exit fullscreen mode
After applying some logic, we get this:
Exit fullscreen mode
Exit fullscreen mode
Now inside our click event function, we will check if there is already a QR code displayed or not. If it is, then we will first clear that QR code and generate a new one. If it’s not present, we can simply generate a new one.
Also, all of this happens only if the user enters some text or if the input value is not empty.
Exit fullscreen mode
You can style the elements the way as you want. Here are the styles that I went for:

Again: The article in itself is helpful but the title very misleading.
A number of issues here.
You’re using a submit button without a form. Adding a form would actually be better too, as you could generate the QR code by also pressing return to submit the form. This is standard, expected behaviour on a form.
You’re repeatedly calling document.querySelector to get the same things. Would be better just to call it once.
Putting all of this together, you can simplify your code considerably.

I agree to everything but the ID approach. Using global definitions is not recommended as there is technically no guarantee it’s gonna be the DOM Element (stackoverflow.com/a/18713391/1236627).
In simple code like your example, you can guarantee it

The problem is that this is viewed from a «small context perspective». In production, as stated, it shouldn’t be recommended to be used.
It goes the same principle as always e.g. Security through Obfuscation is definitely working in the right context. But it’s recommended to be avoided at all costs in programming because it opens up an option to be breached.
But for prod it should be avoided as a guideline. Generally in JS we try to modularize more to enable teams to scale and be free from dependencies from other teams.
In any prod-bound or team-bound contexts where more than 1 person works or anything is supposed to scale in the future this should definitely not be used.

Introduction
Live demo (JavaScript)
You can generate QR Code symbols conveniently on this web page, powered by the TypeScript port of this library.
Features
Available in 6 programming languages, all with nearly equal functionality: Java, Java (fast), TypeScript/ JavaScript, Python, Rust, Rust (no heap), C++, C
Significantly shorter code but more documentation comments compared to competing libraries (a competitive analysis is provided near the bottom of this page)
Supports encoding all 40 versions (sizes) and all 4 error correction levels, as per the QR Code Model 2 standard
Output format: Raw modules/ pixels of the QR symbol
Detects finder-like penalty patterns more accurately than other implementations
Encodes numeric and special-alphanumeric text in less space than general text
Open-source code under the permissive MIT License
User can specify minimum and maximum version numbers allowed, then library will automatically choose smallest version in the range that fits the data
User can specify mask pattern manually, otherwise library will automatically evaluate all 8 masks and select the optimal one
User can specify absolute error correction level, or allow the library to boost it if it doesn’t increase the version number
User can create a list of data segments manually and add ECI segments
Optional advanced features (Java only):
Encodes Japanese Unicode text in kanji mode to save a lot of space compared to UTF-8 bytes
Computes optimal segment mode switching for text with mixed numeric/ alphanumeric/ general/ kanji parts
This library is designed with essentially the same API structure and naming in multiple languages for your convenience: Java, TypeScript, Python, Rust, C++, C. Each language port is pure and doesn’t use foreign function calls. Regardless of the language used, the generated results are guaranteed to be identical because the algorithms are translated faithfully.
For my own convenience when designing and testing the code, the Java language port of the QR Code generator library is considered to be the master reference implementation. The TypeScript, Python, Rust, and C++ ports are translated from the Java codebase, with a balance between writing idiomatic code in the target language but also not deviating too much from the Java code’s design. When in doubt, please consult the Java code to read the more extensive documentation comments and to check what types and values are considered legal.
Java language (SE 7 and above)
Available as a package on The Central Repository: io.nayuki qrcodegen
Online Javadoc documentation: io.nayuki.qrcodegen
This compact, no-dependency library is your one-stop shop for all your QR Code generation needs. To learn how to use the API, please read the demo program’s source code, and maybe skim the library code’s inline Javadoc comments.
For the following practical reasons, Java is my best choice for the reference implementation because it ensures a high degree of correctness and allows writing detailed documentation comments:
Static type checking prevents dumb typos in names and subtly incorrect arguments being passed (such as byte[] vs. BitBuffer ). (Whereas classic Python and JavaScript don’t have static type checking.)
There is a strong and clear separation between public interfaces and private implementation details. (Whereas privacy is only a naming convention in Python, and feasible but hacky/ugly in JavaScript.)
Javadoc is expressive and has a consistent syntax. (Whereas Python, JavaScript, and C++ do not have single dominant syntax for documentation comments.)
Java has good standard libraries for file, image, and network handling, and the language is memory-safe. This makes it easier to build a correct application quickly. (Whereas C++ programming easily gets into third-party library frenzy and undefined behavior hell – even though it does have static typing and proper public/ private just like Java.)
Only the Java implementation of my library contains the advanced segment encoder logic for kanji mode and optimal segment mode switching.
Java language, fast (SE 8 and above)
For heavy-duty use, this alternate Java implementation achieves a speed-up of about 1.5 to 10 times compared to my reference Java library. The API is identical for all the common use cases, unless you are manually creating segments from raw bit streams. For more details about the design and benchmark timings of this work, see the page Fast QR Code generator library.
TypeScript language
The library: qrcodegen.ts
Demo matching all other languages: qrcodegen-output-demo.ts
The demo on this page: qrcodegen-input-demo.ts
The TypeScript code must be compiled into JavaScript in order to be executed in a web browser, Node.js server, etc. Outputting to ECMAScript 5 is supported, though higher versions are more readable.
JavaScript language (5 and above)
The JavaScript port of this library can be found in the releases section on GitHub. The code is machine-generated, compiled from TypeScript but with a bit of hand-tweaking of the header. The code is not in the project’s version control tree. These precompiled pieces of JavaScript code are offered in two flavors: ECMAScript 5 compatibility (for Microsoft Internet Explorer 11) or ES6/2015 compatibility (for all modern web browsers).
Historically, I had a hand-written port of this library for ES5, maintained up to and including version 1.5.0 at commit 1e24fcf67a0d ( 2019-07-16 ). Due to ES5’s lack of classes, the code structure had to be significantly rearranged from the Java code. Then I learned TypeScript, ported the code, and maintained both language ports simultaneously. Later on, I decided to remove the hand-written JavaScript port in favor of compilation from TypeScript – because TS syntax is an easy-to-understand extension of JS, and the TS compiler allows me to use new language features (like ES6) while still being able to compile down to an older version (like ES5).
Python language (3 and above)
Available as a package on PyPI: pip install qrcodegen
Only Python 3 is supported, but historically this library was born as Python 2-and-3 polyglot code. This dual compatibility was maintained throughout development up to and including version 1.6.0 at commit 71c75cfeb0f0 ( 2020-03-05 ).
Rust language
The library: lib.rs
Runnable demo program: qrcodegen-demo.rs
Available as a package on Crates.io: qrcodegen
Online documentation at Docs.rs: qrcodegen
Notes about this Rust port of the library:
Has no crate dependencies, only relying on the standard library.
The source code files are laid out in directories according to the Cargo project format.
The higher level text APIs take &str (UTF-8 byte sequence), whereas the lower APIs take &[char] (Unicode code point sequence).
Unlike the
Rust language, no heap
The library: lib.rs
Runnable demo program: qrcodegen-demo.rs
This implementation combines the object-oriented organization of my other Rust port and the complete lack of heap allocation of my C port. The library works with no_std and is suitable for constrained environments like small microcontrollers and operating system kernels. The user must allocate appropriately sized buffers and then pass them into the library functions to accomplish things. Unlike the C port, this Rust library is completely safe; if the user passes in wrong buffer sizes or misuses the library API, then either a compile-time error or run-time panic is the result. Note that data types like QrCode wrap over a byte buffer, preventing the underlying buffer from being freed until the higher level object is first destroyed.
C++ language (11 and above)
The code requires C++11 to compile due to numerous convenient features unavailable in C++03, such as better handling of temporary values and const instance fields. The code is fully portable because it only depends on the C++ standard library but not any OS APIs (e.g. POSIX ), and it avoids implementation-dependent assumptions on integer widths. The code completely avoids all undefined behavior (e.g. integer overflow, type punning, etc.).
Unfortunately, the library is unsuitable for embedded microcontroller environments (e.g. Arduino) due to the use of the heavyweight STL std:: vector class and dynamic memory allocation. The C port is the one specifically designed to support embedded environments.
C language (99 and above)
Notes about this C port of the library:
Many projects choose the C programming language instead of C++, due to simpler semantics, faster compilation, and more robust development tools (debuggers, etc.). This port of the library serves this market.
The other 5 language ports are facsimiles of each other in terms of code architecture, but this C library had to be written from scratch to avoid dynamic memory allocation and to fit C’s object-less programming paradigm.
The code requires a C99-compliant compiler and standard library to compile. Note that older versions of Microsoft Visual C++ (before the 2013 release) only supported C89, which make it more difficult to use my library.
This code is portable and platform-independent by design. It makes no assumptions on endianness, integer type widths, two’s complement, etc. It only relies on behavior mandated by the C standard, for example the fact that int must be at least 16 bits wide.
This C code uses much more low-level indexing and raw buffer passing than the other language ports, so the correctness of the logic is much less obvious at a glance. The safety of this C library was assured in multiple ways: Being mindful of value ranges and choosing suitably sized integer types, designing arithmetic calculations to carefully avoid overflow, running the code under Clang’s UndefinedBehaviorSanitizer and AddressSanitizer and MemorySanitizer, and feeding millions of random inputs then testing for identical output against other language ports.
Here are a photo and video showing the C port of the QR Code generator library running on a PJRC Teensy 3.1 microcontroller. Remember that in the worst case, rendering a version-40 QR Code requires 8 KB of RAM (including temporary scratch space).
Third-party ports
A number of people have translated this library to other programming languages. These third-party libraries vary in their quality and faithfulness to my original work, and are not backed by my personal guarantee.
QR Code technology overview
The QR Code standard defines a method to encode a string of characters or bytes into a grid of light and dark pixels. The text could be numbers, names, URLs, et cetera. Because the standard uses a 2D barcode, it can store much more information than a traditional 1D barcode. To illustrate for comparison, a 1D barcode usually stores 10 to 20 digits, while a QR code often stores 50 textual characters. Note that a QR Code barcode simply represents static data – the barcode does not inherently cause an action to be executed.
Terminology
Some of the frequently used official terminology have non-intuitive meanings, as summarized below:
Standing for Quick Response, this is a popular international standard (symbology), created by Denso Wave, that specifies how messages are converted to barcodes. “QR Code” is a registered trademark and wordmark of Denso Wave Incorporated.
A single 2D graphical barcode, which results from the QR Code generation process. Informally this is called a “QR code” (without using the word symbol) or a barcode.
A dark or light pixel in a QR Code symbol. Note that a module can be scaled to occupy multiple pixels on a screen or in an image file.
Indicates the revision of the QR Code standard. (The word model here corresponds with the conventional meaning of the word version.) Model 1 QR codes are outdated and essentially never seen. Model 2 QR codes are widespread and dominant. Model 2 also has an extension called Micro QR codes (not implemented in my library). Note that model 1 defines versions 1 through 14, whereas model 2 QR defines versions 1 through 40, allowing much more data capacity.
Generation procedure
The process (and high-level algorithm) for generating a QR Code symbol is as follows:
Choose the text (Unicode string) or binary data (byte sequence) to encode.
Encode the text into a sequence of zero or more segments. A segment in byte mode can encode any data, but using alphanumeric or numeric mode is more compact if the text falls into these subsets.
Based on the segments to be encoded and the ECL, choose a suitable QR Code version to contain the data, preferably the smallest one.
Concatenate the segments (which have headers and payload) and add a terminator. The result is a sequence of bits.
Add padding bits and bytes to fill the remaining data space (based on the version and ECL).
Reinterpret the bitstream as a sequence of bytes, then divide it into blocks. Compute and append error correction bytes to each block. Interleave bytes from each block to form the final sequence of 8-bit codewords to be drawn.
Initialize a blank square grid based on the version number.
Draw the function patterns (finders, alignment, timing, version info, etc.) onto the appropriate modules. This is formatting overhead to support the QR Code standard, and does not encode any user data.
Draw the sequence of (data + error correction) codewords onto the QR Code symbol, starting from the bottom right. Two columns at a time are used, and the scanning process zigzags going upward and downward. Any module that was drawn for a function pattern is skipped over in this step.
Either manually or automatically choose a mask pattern to apply to the data modules. If masking automatically, then all 8 possibilities are tested and the one with the lowest penalty score is accepted. Note that the format information is redrawn to reflect the mask chosen.
We are now finished the algorithmic parts of QR Code generation. The remaining work is to render the newly created barcode symbol as a picture on screen, or save it as an image file on disk.
In the context of the steps above, my QR Code generator library provides the logic to perform steps 3 through 11. The other steps must be performed by the user of the library. I have an interactive page that explains and visualizes the QR Code generation procedure in great detail: Creating a QR Code step by step.
Compared to competitors
Relatively compact implementation – 1260 lines of code for the Java port (without QrSegmentAdvanced), 970 lines for TypeScript, 890 lines for Python, 1340 lines for C++, 1280 lines for C, 1270 lines for Rust. (Each port is independent, so it’s meaningless to add up all the line counts.)
The extra advanced features (kanji mode, optimal segment mode switching) in the Java implementation cost another 290 lines of code and 110 lines of constants
Line counts include the generous amount of comments for functions, comments for blocks of statements, and blank lines – but exclude header comments of author and license info
Contains as few tables of numerical constants as needed – unlike competitors, this implementation does not have tables of: data capacities per version, alignment pattern positions, error correction block sizes, expanded format and version bits, Reed-Solomon divisor polynomials, or finite field exp /log tables
The QR Code and helper objects are all immutable, thus simplifying user operation and reducing errors from accidental misuse of the API
Creates a single segment in numeric, alphanumeric, or byte mode; encodes custom list of segments
The version reviewed was 8f9c1be97466, dated 2021-07-28
About 800 lines of core code in the library
Code is quite concise, minimizing the size of constant tables and avoiding verbose logic
Includes generous comments explaining the overview of behavior
The organization and behavior of subfunctions (such as computing the number of bits and characters, and painting different sets of QR Code modules) are surprisingly similar to my design, despite the fact that he published one year earlier than me and I had never seen his code until months after I published my library
The code is more compact than mine in areas such as the bit buffer and segment encoding, because they are inlined into the QR Code generation workflow instead of being exported as freestanding modules
Creates a single segment in numeric, alphanumeric, or byte mode; cannot encode custom list of segments

qr.js: 800 lines for main QR encoding logic, 110 lines for numerical tables, 300 lines for image export; note that generateFrame() is a 400-line monolithic function
Code includes a good number of comments inside and outside functions
The version reviewed was 18decea6ba9a, dated 2015-11-11. The library has since been renamed to QRious
About 1840 lines of core code in the JavaScript library
qrcode.js: 860 lines of code for main QR encoding logic, 340 lines for numerical tables, 360 lines for HTML and GIF output, 280 lines for binary encoding utilities
Contains no comments at all to describe functions; sparsely contains low-level comments to describe chunks of logic statements
The author has ported the library to multiple languages, but with different levels of features. The JavaScript port appears to be the most feature-complete, the Java port has fewer features but more documentation comments, and others have fewer features and comments.

Creates a single segment in numeric, alphanumeric, or byte mode; creates imperfectly optimized list of segments; encodes custom list of segments
The version reviewed was b79ab5b3e598, dated 2016-03-15
About 2800 lines of core code in the library
builder.py: 900 lines of code for segment encoding, bitstream formatting, ECC generation, module drawing, symbol penalty calculation; 500 lines for export logic to various image formats
__init__.py: 620 lines for mostly character encoding logic, some one-liner wrapper methods for exporting images, and long documentation comments
tables.py: 750 lines of almost entirely numeric constants
Generally speaking the function-level documentation comments are long (and longer than my typical writing), there are comments every 5 or so lines within functions to describe the algorithmic processes (just like I do), but the implementation seems to use a lot of code just to implement basic behaviors
The version reviewed was 467f9a2a3c04, dated 2016-02-26
About 2800 of core code in the library, when the embedded pieces of test and benchmark code are removed
Includes plenty of documentation comments throughout, and at least 200 lines of tables of numbers in ec.rs
Apparently supports encoding Micro QR Codes and kanji mode

The most popular C library for QR Code encoding by far
Has third-party wrappers for various high-level languages, and numerous patches over the years
Uses dynamic memory allocation, unlike my zero-allocation C library
Supports even more advanced features absent from my library, such as Micro QR codes and structured append mode
Code seems confusing with over 50 public API functions

Frequently Asked Questions
What is a QR code? QR code is short for Quick Response code. QR codes are barcodes made up of colored squares on a contrasting background, which can be scanned using the camera on your mobile phone. The data encrypted in QR codes normally directs you to a website, app, phone number, or email address. They save time, and reduce the risk of error, by eliminating the need to manually enter a URL. They are commonly used in restaurants for non-contact menus, as trackable promotions for retail companies, and you will often see them in newspapers, on billboards, and even on clothing. What is a QR code generator? A QR code generator is a tool to help you quickly and easily create a custom QR code. Once you have finished generating your QR code you can download it and embed it in your website, landing page, or email newsletter, or you can print and display it. Will my QR code expire? As long as the data you are encrypting doesn’t expire, then the QR code will not expire. If, for example, you encrypt a URL that, at some point, no longer exists, those who scan the QR code will be redirected to a 404 page. Are QR codes free? Yes, our tool generates QR codes for free. There are no limitations on the number of QR codes you can create using our tool.

Branded QR codes get up to 40% more scans than traditional black and white QR codes. As a way for people to trust your QR code more, adding a logo to it is a necessity for brands.
Track instant Data
Data is an important part of your business operations, without it you will lose many opportunities for your enterprise endeavors. With dynamic QR codes you can always track important scanning information and adjust all your campaigns instantly by updating its content. You can track data as time of scan, number of scan, location and device type (iPhone/ android).
Dynamic QR codes
If you use QR codes to expand your marketing scope, then the use of Dynamic QR codes is the best QR code type that you can apply! With it, you can instantly change the URL or content behind your QR code without needing to create a new set of codes. Thus, making it a great investment that saves you money and time on printing.

Get more scans! Improve your QR code marketing
A Call to Action : Adding a “call to action” to your QR code is one effective way to boost your QR code marketing strategy and attain more scans from people. As many brands tend to forget adding a “call for action” in their QR codes, only few people are scanning their QR codes. You can create a short yet compelling call to action like scan me, scan and win, scan and view more into your QR code to give a definitive overview for the people who will be scanning them.
QR Code Sizing : To ensure that people can automatically scan your QR code with just one try, always take a look the size of your QR code you are displaying. As a QR code gives a digital dimension to your content, you should always make sure that people can easily see them at a distance. To be able to scan your QR code, always ensure to resize it at least 1.2 inch (3-4 cm) in dimension.
QR Code Positioning : To improve your marketing stance, being conscious about the positioning of your QR code! is a necessity that every marketer needs to learn. To make most of your QR code you must also place the QR code where customers can see and scan it easily. QR codes that are placed too high or too low where the customers will have to crouch to scan will discourage them from scanning the QR code
QR Code Design Customization : The design of every material that is associated with your company is important for your company’s success. Therefore, QRTiger QR code generator online allow you to generate a customized QR code that suits well with your brand. Create brand awareness by customizing your QR code design, now!
Frequently Asked Questions
What is a QR code and why do I need one?
A QR code stands for ‘Quick Response Code’ and is a 2-dimensional barcode type invented by Denso Wave in 1994. You can get more information at Wikipedia. Today QR codes are used a lot to give a digital dimension to a product or flyer that leads to a URL.
What is the difference between a static and dynamic QR code?
With a dynamic QR code you can track data and you can edit your content at any time to a new content with the same category, this saves you time and money on printing. With a static QR the user will go direct to your embedded data i.e. URL and text, however data cannot be tracked and you are unable to edit your URL. For marketing, Dynamic QR codes are more useful as you can track the following pertinent scan statistics: the number of scans, the time when the user scanned, the location of the scan (city/country) and the device type of the user (iPhone/Android).
Can I switch from a static to a dynamic QR code?
No, once you select and make a static QR we cannot change it to a Dynamic QR code. Static and dynamic QR codes are two different QR code types.
How many times can my can my dynamic QR been scanned?
You can scan your dynamic QR codes as many times as you like until your paid subscription expires.
Can I delete a dynamic QR code?
Yes, if you use it for less than 8 scans you can still delete it on the track data page.
My QR code is not working, what can I do?
There are many reasons why a QR code is not working correctly. First check your entered data. Sometimes there are little typos in your URL that break your QR code. Make sure that there is enough contrast between the background and foreground of the QR code. The foreground should always be darker than the background.
Can I save QR codes as a template and can I delete a template?
Yes, you can make a template, this saves you time next time you make a QR code and you can easily delete your templates. Simply hover over the template and a cross will appear to delete the template.
How many free static QR codes can I make?
You can make as many static QR codes as you want; your QR code will never expire and will be valid for a lifetime.
What is the best format for the logo of the QR code?
You can add a logo to your QR code; however it is important that your logo is in a square format otherwise it might look stretched. It is also important to note whether you upload your logo in JPEG or PNG format. It is recommended to have a logo around 500KB to 1 MB.
How to apply for Alipay WeChat 2-in-1 aggregated payment QR code collection code?
Alipay WeChat aggregated QR code collection code application is very simple, just save your own WeChat, Alipay collection code, upload the payment picture, you can get the aggregated QR code
What are the benefits of the two-dimensional rainbow WeChat Alipay aggregated payment two-in-one collection code for merchants?
For merchants, there is no intermediate handling fee, and the collection is directly transferred to the merchant’s change account (Alipay, WeChat), without the need for a third-party company to withdraw cash. And the combined QR code can automatically identify the user’s scanning method, WeChat scan code will use WeChat payment, Alipay scan code will use Alipay payment. Very convenient and simple.
Will uploading the WeChat Alipay aggregated two-in-one payment collection code on the website reveal user privacy information?
Will not. The collection code is a personal QR code for payment, which is a way for customers to transfer money to the other party. It is the same as the collection code that merchants usually show to customers.
Can I make a File QR Code for a PDF, JPEG, PNG, Word, Excel?
You can make a file QR code as a PDF QR Code, Word QR Code, Excel QR code or Video QR Code for your business, you can also make a Jpeg QR code or a PNG QR code or any other image file.

To make a menu QR code for your restaurant and bar menu is easy, best is to upload a PDF, Jpeg or PNG of your menu, you can update your menu QR code any time even after your menu has been generated.
QR Code and 2D Code Generator
This page is an online two dimensional code generator which is written in PHP. It can generate QR Code, Data Matrix, Aztec Code and Micro QR Code.
Using the form on this page, you can create two dimensional code images that trigger various actions on the scanner device. Don’t forget to install Qrafter or Qrafter Pro (why two versions?) to scan and generate QR Codes if you have an iPhone or iPad. So far, this page created 4,617,122 codes since I started counting in January, 2010.
Please be sure to read the Notes and FAQ sections below before requesting help in the comments if you encounter any problems with code generation (Especially for Micro QR Codes or backslash characters you may encounter on some codes!).
This page is very popular and because of that, it gets an incredible amount of comment spam. Sometimes legitimate comments can get caught as spam and I can miss them, so if your comment does not appear after some time, you can contact me from the email address on my contact page.
READ THIS FIRST:
I am getting many questions about scanning the codes created on this generator. Most of them are about some problem with the scanner not detecting the content of the code properly. This generator follows established standards strictly and most scanner apps except Qrafter and Qrafter Pro for iOS don’t follow those standards completely. So, if you somehow end up with an unexpected result after scanning a code, it is because that your scanner was developed lousily. If you are on iOS, use Qrafter or Qrafter Pro for guaranteed standards compatibility. For other platforms, please contact the developers of your scanner app to tell them to start following the standards that were established for a reason.
Notes:
You can follow me or Qrafter on Twitter.
QR Code is far more widespread than Data Matrix, Aztec Code or Micro QR Code. Actually Micro QR Code is rarely used and is only given here as a technology preview. If you want to create a campaign for your products using a 2D Code, make sure that you are using QR Codes, not the other types.
Data Matrix and Aztec Code have significantly lower capacity (4096 alphanumeric characters for QR Code, 3067 for Aztec Code and 2335 for Data Matrix), so if you would like to encode a lot of text, select QR Code.
To create the best readable code for long URLs, use one of the URL shortening services so that the resulting code is as small as possible. I personally prefer bit.ly over the others.
Micro QR Code cannot hold more than 35 numeric and 21 uppercase alphanumeric characters, and it can hold even less characters when you use lowercase characters. When encoding a URL into a Micro QR Code, try using all uppercase characters for longer URLs. I don’t know of a scanner that supports Micro QR Code though.
If your input cannot be encoded, the generator will give a warning. In that case, lower the character count in your input and try again.
If your device cannot interpret the encoded 2D Code properly, it probably means your scanner program is written poorly or does not have the capability of decoding that particular code format; or your device does not accept that action, because all codes created by this script and the content within them are compliant to all necessary published standards (vCard standards, URL encoding schemes, NTT DoCoMo standards, etc.).
While we are talking on standards, let me open the topic up a little bit more. Sadly most scanners out there do not follow special character escaping standards. Characters like “:” or “;” are special characters in vCard, meCard or vEvent specifications, and they should be properly escaped for the input to be interpreted correctly. This generator follows these standards correctly, and so a URL field like “http://example.com” becomes “http\://example.com” after escaping. The problem is, some scanners do not know how to handle this escaped character and break altogether. If you encounter such problem, select No for Escape Special Characters in vCard, meCard or vEvent creation. But while you will be able to read those QR Codes in broken scanners, be aware that, your 2D Code will not be standards compliant and you may not be able to add a URL that includes a second colon (for example as a port number separator) or semicolon when you do that. If you are on iPhone or iPad, I strongly suggest that you ditch your broken scanner and download Qrafter or Qrafter Pro. They are fully compliant to said standards. This way, I hope that developers will be forced to create scanners that obey standards that were established for a reason.
Data Matrix, Aztec Code and Micro QR Code do not support characters other than ASCII because of their spec, so if your input has international characters, always use QR Code. Another caveat of Micro QR Code is that, it is not supported by most of the scanner programs out there. As for Kanji and Cyrillic characters, again, only QR Code should support them.
Always use dark colors for foreground color and light colors for background color. If there is not enough contrast between foreground and background colors, your device will most probably fail to decode the code. Another warning: The EPS version I had to use does not support transparency, so you should use another format if you are going to have transparent foreground or background in your codes.
Twitter Profile Image Overlay option overlays your Twitter profile image onto a code that includes your Twitter profile URL. Images created with this option will behave very oddly with vector image formats. You have been warned! 🙂
Currently you can do the following actions with 2D codes generated with this form:
You can change the block size of the generated image to make it bigger or smaller. Also, you can change the margin size of the image to add more quiet zone if your decoder cannot decode it (Especially Data Matrix seems to need bigger margin sizes). Error correction level for QR Code (ignored for other code types) can be set to 4 different values and higher values may cause the image to be decoded slightly slower. The 4 values can be explained like this:
You can choose PNG, PDF, SVG or EPS outputs. SVG will output a vector image XML file, and you can edit it in applications like Adobe Illustrator or Inkscape.
Please be aware that while I make checks for illegal characters to protect my server, I do not check your input for a meaningful value.
The image generation is done using third party encoders. I have only written a handy PHP front end that formats your input and passes it to these encoders.
A note about printing from Roy, a fellow user of this generator: When codes are generated, they are created in RGB (my note: yes even if they are black and white, they are in RGB colorspace) and if they are used in printing, they should be converted to grayscale or CMYK so that, when printed, only the black plate is used. This ensures the highest edge resolution, particularly in smaller sizes.
QR Code Scanners:
The best scanner apps for iPhone and iPad are Qrafter and Qrafter Pro. They are available on the App Store. They are designed for both iPhone and iPad and Qrafter is free with advertisements, while Qrafter Pro is paid with no advertisements. They are able to understand all actions on this generator (and more) and are the most advanced scanners for QR Codes on iPhone and iPad.
For Android, the best option seems to be the Barcode Scanner app from ZXing.
For Nokia Maemo/Meego, you can use Mbarcode according to Ryks, another commenter.
For other devices, you may find one, suitable for your device from Kaywa or QuickMark.

Here is an updating list of frequently asked questions.
Q: Can I change the content of a code I created if I find a mistake?
A: The codes generated on this generator are standalone, which means they have no connection to this generator after being generated. This also means they include the content directly inside them, and if the content needs to change, the generated code image will change. Please test your code images with as many devices and scanner apps as possible to avoid any problems after printing the codes.
Q: Why do I get unwanted characters like a backslash (\) or semicolon (;) in the result when I scan a QR Code?
A: You are using a QR Code reader that cannot parse the contents of QR Codes correctly. Many readers are especially weak at parsing vCards. Use a proper app from the QR Code Scanners list on this page.
Q: Do you harvest the information I enter into this form?
A: No, I don’t use the information you enter to this form in any means. After you create your 2D Code, the information is removed from my server.
Q: Can I track the scan information for the 2D Codes I create on this generator?
A: You can’t track the 2D Codes you create on this generator unless you create your own trackable URL (for example a bit.ly URL) and then enter that URL to generate a QR Code for it on this page.
Q: Do the 2D codes that were created on this generator have an expiration date?
A: No, all codes generated on this generator can be used as long as you want.
Q: Can I use the codes I create on this generator commercially? Do I need to pay any fees?
A: You can use the codes created on this generator both commercially and personally. There are no fees to pay. The only favor I ask back is the promotion of Qrafter or Qrafter Pro on your site as your recommended reader app for iOS devices. But it is only a request, you are not obliged to do that. 🙂
Q: What is the minimum size for a QR Code so that it can be scanned with all devices?
A: The answer to this question cannot be given with exact proportions. New devices with autofocus cameras can scan very small QR Codes, but old devices that don’t have autofocus cameras will have problems with scanning codes smaller than one or two inches. Also it depends on the size of the information that you put into the QR Code. You need to test your QR Code with many devices, old and new to find the best compromise.
Q: Can I overlay an image on top of the QR Code like the one in “Twitter Profile Image Overlay” action of this generator?
A: Yes you can. Create a QR Code with highest error correction and select a vector output. This way, using your preferred image editor, you can overlay an image that’s up to 30% of the QR Code. Be careful not to overlay the image on top of the 3 alignment squares though.
