The digitalization of books and documents is one of the endeavors our generation has taken on itself. And between various e-book formats, EPUB is one of the most used ones.

However, like any other file, EPUB can get corrupt and thus inaccessible. This isn’t exactly a common thing, as the EPUB archive isn’t the most complex thing ever, but it can happen from time to time.

If you’re in need of fixing the corrupt EPUB file, we have a few steps you can try out, so keep reading.

3. Extract the EPUB file and archive it again

  2. During the installation, don’t forget to allow the application to create the shortcut in the contextual menu.
  3. Right-click on the corrupted EPUB file, and choose Extract here.fix corrupt epub
  4. Select all extracted files (it should be 3), right-click on one of them, and choose Add to archive.fix corrupt epub
  5. Replace the extension file format to epub and click OK at the bottom.fix corrupt epub

This simple trick seemingly helped a lot of users who were having a hard time with a corrupted EPUB file. The step is rather simple and all you need is an archiver, like WinRar or WinZip.

Basically, what you need to do is extract the content from an EPUB file and archive it again with the said third-party archiver. That will, hopefully, make it accessible again.

Although, a lot of this depends on the capabilities of your EPUB reader.
