This Symfony lets you generate QR Codes using the endroid/qrcode library.
It provides the following features.

  • Configure your defaults (like image size, default writer etc.)
  • Generate QR codes quickly from anywhere via the factory service
  • Generate QR codes directly by typing an URL like /qrcode/<text>.png?size=300
  • Generate QR codes or URLs directly from Twig using dedicated functions


Use Composer to install the library. Symfony Flex
will set up the configuration and routing for you.

$ composer require endroid/qrcode-bundle


The bundle makes use of a factory to create QR codes. The default parameters
applied by the factory can optionally be overridden via the configuration.

    writer: 'png'
    size: 300
    margin: 10
    foreground_color: { r: 0, g: 0, b: 0 }
    background_color: { r: 255, g: 255, b: 255 }
    error_correction_level: low # low, medium, quartile or high
    encoding: UTF-8
    label: Scan the code
    label_font_size: 20
    label_alignment: left # left, center or right
    label_margin: { b: 20 }
    logo_path: '%kernel.root_dir%/../vendor/endroid/qrcode/assets/images/symfony.png'
    logo_width: 150
    validate_result: false # checks if the result is readable

Generate via factory

Now you can retrieve the factory from the service container and create a QR
code. You can also pass options to override defaults set by your configuration.

$qrCode = $qrCodeFactory->create('QR Code', ['size' => 200]);

Generate via URL

The bundle provides a controller that allows you to generate QR codes simply
by opening an URL like /qrcode/<text>.png?size=300. You can configure the
prefix in your routing file and pass any of the existing options via query string.

Generate via Twig

The bundle provides a Twig extension for generating a QR code URL, path or data
URI. You can use the second argument of any of these functions to override any
defaults defined by the bundle or set via your configuration.

<img src="{{ qrcode_path(message) }}" />
<img src="{{ qrcode_url(message, { writer: 'eps' }) }}" />
<img src="{{ qrcode_data_uri(message, { writer: 'svg', size: 150 }) }}" />
