epub2sphinx

epub2sphinx is a tool to convert epub files directly into HTML sites using Pandoc and Sphinx. It can use any of pre-existing Sphinx themes (like these) for the generated HTML site.

It uses Pandoc for converting HTML data inside epub files into ReST files and then uses Sphinx to convert them into a HTML site.

It creates a directory structure similar to what sphinx-quickstart generates by default.

Built during FOSSHack 21 to solve this issue.

Usecase

epub2sphinx can be used to convert public domain or CC-licensed epub files into static web pages that allows people to read them online. This will be useful for sites like Project Gutenberg or FreeTamilEbooks. Eventhough Project Gutenberg has an option to read online, it is very plain. Using Sphinx allows us to make use of any default or custom sphinx theme to make it look better.
