A PHP class to generate PDF files from HTML with Unicode/UTF-8 and CJK support
mPDF is a PHP library which generates PDF files from UTF-8 encoded HTML.
Note: If you are viewing this file on mPDF Github repository homepage or on Packagist, please note that the default repository branch is
developmentwhich can differ from the last stable release.
mPDF 7 requires PHP
^5.6 || ~7.0.0 || ~7.1.0 || ~7.2.0. PHP
gd extensions have to be loaded.
Additional extensions may be required for some advanced features such as
zlib for compression of output and
embedded resources such as fonts,
bcmath for generating barcodes or
xml for character set conversion
and SVG handling.
mPDF has some problems with fetching external HTTP resources with single threaded servers such as
php -S. A proper
server such as nginx (php-fpm) or Apache is recommended.
Official installation method is via composer and its packagist package mpdf/mpdf.
$ composer require mpdf/mpdf
The simplest usage (since version 7.0) of the library would be as follows:
<?php require_once __DIR__ . '/vendor/autoload.php'; $mpdf = new \Mpdf\Mpdf(); $mpdf->WriteHTML('<h1>Hello world!</h1>'); $mpdf->Output();
This will output the PDF inline to the browser as
All configuration directives can
be set by the
$config parameter of the constructor.
It is recommended to set one's own temporary directory via
tempDir configuration variable.
The directory must have write permissions (mode
775 is recommended) for users using mPDF
Warning: mPDF will clean up old temporary files in the temporary directory. Choose a path dedicated to mPDF only.
<?php $mpdf = new \Mpdf\Mpdf(['tempDir' => __DIR__ . '/tmp']);
By default, the temporary directory will be inside vendor directory and will have correct permissions from
post_install composer script.

vendor/bin/phpunit from the command line while in the mPDF root directory.
Any assistance writing unit tests for mPDF is greatly appreciated. If you'd like to help, please
note that any PHP file located in the
/tests/ directory will be autoloaded when unit testing.
