About EPUB Cover Changer (.site)

What we do
We make one thing: a tool that adds, replaces or repairs the cover inside an EPUB file. Blank covers on a Kindle, grey thumbnails on a Kobo or a missing cover from a converter usually come down to how the book file declares its cover image. The tool rewrites that part (the image, its manifest entry, the cover metadata and the cover page) and leaves the chapters untouched.
How we test it
Each change follows the EPUB 3 specification. Our test books are validated with EPUBCheck (version 5.4.0) before and after a cover change, and the output has to come back with zero errors and zero warnings. Encrypted (DRM) books are refused, not altered.
Your files
The book is opened, changed and saved inside your browser. It's never uploaded. We record anonymous usage counts and nothing about your books.
Reach us
Questions, a book that didn't come out right, or a reader whose cover still won't update: support@epubcoverchanger.site. Telling us the device and the original source of the book helps.
