Build Status Total Downloads Latest Stable Version

This is an easy to use, non-bloated, framework independent, barcode generator in PHP. It uses zero(!) composer dependencies and is only a handful of files. Probably the reason that this is the most downloaded barcode generator for PHP on Packagist. ;)

It creates SVG, PNG, JPG and HTML images, from the most used 1D barcode standards.

The codebase is based on the TCPDF barcode generator by Nicola Asuni. This code is therefor licensed under LGPLv3.

No support for...

  • No support for any 2D barcodes, like QR codes.
  • We only generate the 'bars' part of a barcode, without text below the barcode. If you want text of the code below the barcode, you could add it later to the output of this package.


Install through composer:

composer require picqer/php-barcode-generator

If you want to generate PNG or JPG images, you need the GD library or Imagick installed on your system as well.


Initiate the barcode generator for the output you want, then call the ->getBarcode() routine as many times as you want.

require 'vendor/autoload.php';

// This will output the barcode as HTML output to display in the browser
$generator = new Picqer\Barcode\BarcodeGeneratorHTML();
echo $generator->getBarcode('081231723897', $generator::TYPE_CODE_128);

Will result in this beauty:
Barcode 081231723897 as Code 128

The getBarcode() method accepts the following parameters:

  • $barcode String needed to encode in the barcode
  • $type Type of barcode, use the constants defined in the class
  • $widthFactor Width is based on the length of the data, with this factor you can make the barcode bars wider than default
  • $height The total height of the barcode in pixels
  • $foregroundColor Hex code as string, or array of RGB, of the colors of the bars (the foreground color)

Example of usage of all parameters:


require 'vendor/autoload.php';

$redColor = [255, 0, 0];

$generator = new Picqer\Barcode\BarcodeGeneratorPNG();
file_put_contents('barcode.png', $generator->getBarcode('081231723897', $generator::TYPE_CODE_128, 3, 50, $redColor));

Image types

$generatorSVG = new Picqer\Barcode\BarcodeGeneratorSVG(); // Vector based SVG
$generatorPNG = new Picqer\Barcode\BarcodeGeneratorPNG(); // Pixel based PNG
$generatorJPG = new Picqer\Barcode\BarcodeGeneratorJPG(); // Pixel based JPG
$generatorHTML = new Picqer\Barcode\BarcodeGeneratorHTML(); // Pixel based HTML
$generatorHTML = new Picqer\Barcode\BarcodeGeneratorDynamicHTML(); // Vector based HTML

Accepted barcode types

These barcode types are supported. All types support different character sets or have mandatory lengths. Please see wikipedia for supported chars and lengths per type.

Most used types are TYPE_CODE_128 and TYPE_CODE_39. Because of the best scanner support, variable length and most chars supported.

  • TYPE_CODE_32 (italian pharmaceutical code 'MINSAN')
  • TYPE_CODE_39
  • TYPE_CODE_93
  • TYPE_CODE_128
  • TYPE_CODE_128_A
  • TYPE_CODE_128_B
  • TYPE_CODE_128_C
  • TYPE_EAN_2
  • TYPE_EAN_5
  • TYPE_EAN_8
  • TYPE_EAN_13
  • TYPE_ITF14 (Also known as GTIN-14)
  • TYPE_CODE_11

See example images for all supported barcode types

A note about PNG and JPG images

If you want to use PNG or JPG images, you need to install Imagick or the GD library. This package will use Imagick if that is installed, or fall back to GD. If you have both installed but you want a specific method, you can use $generator->useGd() or $generator->useImagick() to force your preference.


Embedded PNG image in HTML

$generator = new Picqer\Barcode\BarcodeGeneratorPNG();
echo '<img src="data:image/png;base64,' . base64_encode($generator->getBarcode('081231723897', $generator::TYPE_CODE_128)) . '">';

Save JPG barcode to disk

$generator = new Picqer\Barcode\BarcodeGeneratorJPG();
file_put_contents('barcode.jpg', $generator->getBarcode('081231723897', $generator::TYPE_CODABAR));

Oneliner SVG output to disk

file_put_contents('barcode.svg', (new Picqer\Barcode\BarcodeGeneratorSVG())->getBarcode('6825ME601', Picqer\Barcode\BarcodeGeneratorSVG::TYPE_KIX));
