ePubCrawler takes an InDesign document, and converts it to a collection of XHTML and CSS files. There is also eCanCrusher, which comes with ePubCrawler. You can then drag-drop an EPUB folder onto the eCanCrusher application icon, and it will convert the folder into an .epub file. ePubCrawler is very flexible and can be reconfigured to generate a wide range of possible fixed-layout EPUB variants. If you don't like what it does, you can change things.
- Fixed bug where special characters were not correctly translated in CS5 and higher.
- Fixed bug where hyperlinks in the text that had a style applied ended up with the and swapped, resulting in invalid XHTML.
