EPUBCheck: About

EPUBCheck is open source software, maintained by the DAISY Consortium on behalf of the W3C.

Visit the development homepage.

§ Support Us

Financial support is critical to the development of EPUBCheck, the tool we all use to validate EPUB files.

We need to make sure that the resources are adequate to both update the tool and provide for its continued maintenance over the next two years.

Please help us fund and support EPUBCheck, and join the list of donors!
