3. Extract the EPUB file and archive it again

Let’s start with a simple trick which, 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.

Here’s what you need to do, step-by-step:

  1. Download and install WinRar or 7zip.
    • During the installation, don’t forget to allow the application to create the shortcut in the contextual menu.
  2. Right-click on the corrupted EPUB file and choose Extract here from the contextual menu.fix corrupt epub
  3. Select all extracted files (it should be 3), right-click on one of them, and choose Add to archive.fix corrupt epub
  4. Replace the extension file format to epub and click OK at the bottom.fix corrupt epub

4. Convert EPUB

Other users managed to completely salvage the content of a corrupted EPUB file by converting it. The usual procedure is to convert it to a PDF format and move from there.

However, you can even convert an EPUB file to, well, EPUB. It sounds ludicrous but that’s allegedly a way to solve the problem. So, if the PDF file format doesn’t suit your needs, you can use a converter to replicate the corrupted file.
