Build Status

A beautiful demo is worth a thousand words:


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.

    • GCC >= 4.4.6
    • I heard about successful build with Clang
