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 releases page to get the latest distribution.
EpubCheck 4.0.2 is the latest recommended version to validate both EPUB 2 and 3 files.
Documentation on how to use EpubCheck, to contribute to the project or to translate messages is available on the EpubCheck wiki.
Technical discussions are hosted on the EpubCheck Google Group
