EpubCheck is a tool to validate EPUB files. 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 or used as a Java library.
Check the release page to get the latest distribution.
To build epubcheck from the sources you need Java Development Kit (JDK) 1.6 or above and Apache Maven (version 3 or higher is recommended).

EpubCheck is a project coordinated by IDPF. 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.
