FPDF
FPDF
FPDF is a solution written in PHP that allows you to generate PDF documents directly from PHP, so you can use the PDFlib library. The F of FPDF means free, so you can use it for any purpose and modify it to your liking to satisfy your needs. FPDF does not need any extension for PHP (except Zlib to enable compression and GD for GIF support) and works with PHP5 (≥ 5.1), PHP7 and PHP8. The tutorials will allow you to quickly access FPDF. FPDF generates documents in many other languages apart from the Western European ones, like Central, Cyrillic, Greek and Baltic, if they have TrueType or Type1 sources with the set of appropriate characters. UTF-8 is also available. The speed of generation of a document is less than that of PDFlib. Without the resentment, however, is very reasonable and is adequate for the majority of cases, unless its documents are specifically compiled or extended.Starting Price: Free -

DocRaptor
Expected Behavior
There are several popular free HTML-to-PDF libraries including wkhtmltopdf, PhantomJS, and Chrome Headless / Puppeteer.

This fundamental difference has a tremendous impact on PDF functionality such as page breaks, headers and footers, and variable page sizes. Our conversion engine provides layout and styling options (including CSS Paged Media support) that the open-source PDF engines simply cannot match.
