pdf2htmlEX renders PDF files in HTML, utilizing modern Web technologies, aims to provide an accuracy rendering, while keeping optimized for Web display.

It is optimized for modern web browsers such as Mozilla Firefox & Google Chrome.

This program is designed for scientific papers with complicate formulas and figures, so a precise rendering is also the #1 concern. But of course general PDF files are also supported.


  • Single HTML file output
  • Precise rendering
  • Text Selection
  • Font embedding & reencoding for Web
  • Proper styling (Color, Transformation...)
  • Optimization for Web

Not supported yet

  • Type 3 fonts
  • Non-text object (Don't worry, they will be rendered as images)

Get started

Fontforge-git is no longer required, a recent version should be OK


There is a Ubuntu PPA set up at here.


Special thanks to Arthur Titeica for the AUR Package.
