pdf2htmlEX

Build Status

A beautiful demo is worth a thousand words:

Introduction

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

pdf2htmlEX is best for text-based PDF files, for example scientific papers with complicated formulas and figures. Text, fonts and formats are natively perserved in HTML such that you can still search and copy. The generated HTML file is static, Javascript is not required.

Why HTML ?

HTML, together with CSS and Javascript, is much more open and flexible than PDF. Almost everything can be customized.

  • Embedding documents to web pages with consistent theme and behavior
  • Cross references to other documents are much easier and intuitive
  • More functions to the document with Javascript, e.g. access control, animation, statistics

Readers can also be benefitted

  • Read while downloading
  • Plugin-free

Get started

Install

Thanks to all packagers!

Build from source

Dependency

  • CMake, pkg-config
  • GNU Getopt
  • compilers support C++11, for example
  • GCC >= 4.4.6
  • I heard about successful build with Clang
  • poppler with xpdf header >= 0.20.0 (compile with --enable-xpdf-headers)
  • Install libpng (and headers) BEFORE you compile poppler if you want background images generated
  • Install poppler-data if your want CJK support
  • fontforge (with header files)
  • git version is recommended to avoid annoying compilation issues
  • [Optional] ttfautohint
  • run pdf2htmlEX with --external-hint-tool=ttfautohint to enable it
  • [For Windows]
  • Cygwin
  • or MinGW, with some modifications to pdf2htmlEX. See pdf2htmlEX on TeX Wiki (in Japanese), special thanks to Haruhiko Okumura
