EpubCheck

EpubCheck is a tool to validate IDPF EPUB files, version 2.0 and later. It can detect many types of errors in EPUB. OCF container structure, OPF and OPS mark-up, and internal reference consistency are checked. EpubCheck can be run as a standalone command-line tool, installed as a Java server-side web application or used as a Java library.

Note that you must be able to run Java from the command-line and be familiar with command-line tools to use this effectively. There are step-by-step guidelines available.

Most of the EpubCheck functionality comes from the schema validation tool Jing and schemas that were developed by IDPF and DAISY. Initial EpubCheck development was largely done at Adobe Systems.
