Microsoft Edge used to allow you to read your favorite eBooks directly in the browser. Microsoft made opening EPUB files possible through the Windows 10 Creators Update, which brought a slew of features including EPUB file format support. 

Adding EPUB support to Edge was a strategic decision because Microsoft sold eBooks in the Microsoft Store app. In July 2019, once Microsoft removed eBooks entirely, they also ended support for EPUB files, which means you can no longer open eBooks with the .epub file extension with Microsoft Edge.

Fortunately, you can open EPUB files on Windows using an application that supports them, convert the EPUB files to other supported file formats, and then read them on your PC.

Open EPUB Files by Renaming .ePub to .zip

If you don’t want to open EPUB files on Windows using third-party software, you can rename the file from .ePub to .zip and open it with a file compression program like 7-Zip.

  2. Right-click the .ePub file and select Rename.
  1. Replace the .ePub suffix with .zip and press Enter

You can also use an online tool like ezyZip to convert the ePub file to a .zip file.

Then, use 7-Zip, WinRAR, WinZip, or your preferred file compression program to extract the contents of the file, which are in HTML format. (See the differences between the many archived compressed file formats).

Open EPUB Files by Converting the EPUB file to PDF

You can also convert an EPUB file into a PDF and open it on your PC. Some programs that can convert EPUB to PDF or other eBook reading formats include Calibre, Zamzar, and Online eBook Converter.

  1. If you choose Calibre, add the EPUB file you want to convert into the program, select Convert books > Convert individually
