How to Recover and Repair EPUB Files? Top Guide Here

Due to its many advantages such as portability and low cost, e-books have become the first choice for many people to read. EPUB is one of the most common formats in e-books. But what if your EPUB file suddenly gets corrupted? This article will guide you on how to repair corrupted EPUB files and how to retrieve lost EPUB files.

EPUB stands for Electronic Publication and is an e-book file with the .epub extension. Almost all devices support opening EPUB files using the corresponding application. However, EPUB files may also be corrupted or lost like other files. The following will introduce several ways to repair corrupted EPUB files.

Method 1: Unzip and repackage the corrupted EPUB file

Sometimes, EPUB files are corrupted due to messy file structure. You can unzip the EPUB file and repackage it to rebuild the file structure. This method requires the use of third-party tools such as WinRAR or 7z. The following steps will demonstrate how to use WinRAR to repair corrupted EPUB files:

Step 1: Start WinRAR and add the corrupted EPUB file to the application.

Step 2: Right-click the file and select "Extract to specific folder".

Step 3: In the next window, you can choose to change the path to the decompressed file. Click OK to confirm.

Step 4: Once you are done, find the folder you created, right-click it, and select "Add to Compressed File".

Step 5: Select "ZIP" in the "Compressed File Format" section. Then, change the file extension to ".epub" and click OK to confirm.

After that, use your favorite reader to open the EPUB file and see if it can be opened normally.

Method 2: Use Calibre to convert corrupt EPUB files

Another possible solution is to convert the corrupted EPUB file to PDF file format, which will keep the contents intact and secure. If you use Calibre to read EPUB files, you can easily repair corrupted EPUB files using this tool.

Step 1: Open Calibre on your computer and select the corrupted EPUB file.

Step 2: Select Convert Books in the top toolbar and select Convert individually.

Step 3: Change "Output Format" to "PDF" in the next window, and click "OK" to save the changes.

Try to open the converted PDF file to verify the file contents. Alternatively, you can choose another professional PDF converter, such as MiniTool PDF Editor, or repair EPUB files using an online EPUB to PDF converter.

If neither of the above works, you can try opening the corrupted EPUB file with another reader, or re-download the file to directly repair the corrupted EPUB file.
