mPDF Manual


mPDF is a PHP library which generates PDF files from UTF-8 encoded HTML.

It is based on FPDF and HTML2FPDF with a number of enhancements.

The original author, Ian Back, wrote mPDF to output PDF files ‘on-the-fly’ from his website, handling different languages. It is slower than the original scripts e.g. HTML2FPDF and produces larger files when using Unicode fonts, but support for CSS styles etc. and has been much enhanced – see the features.

About CSS support and development state

mPDF as a whole is a quite dated software. Nowadays, better alternatives are available, albeit not written in PHP.

Use mPDF if you cannot use non-PHP approach to generate PDF files or if you want to leverage some of the benefits of mPDF over browser approach – color handling, pre-print, barcodes support, headers and footers, page numbering, TOCs, etc. But beware that a HTML/CSS template tailored for mPDF might be necessary.

If you are looking for state of the art CSS support, mirroring existing HTML pages to PDF, use headless Chrome.

mPDF will still be updated to enhance some internal capabilities and to support newer versions of PHP, but better and/or newer CSS support will most likely not be implemented.
