Windows 10 has no default app to read EPUB files. You can actually open an EPUB file using Microsoft Edge. But, reading an ebook with Microsoft Edge is not a good idea since it is less convenient, especially for ebooks with lots of pages. There are a bunch of EPUB reader apps for Windows 10. We have compiled them in the list below.
EPUB itself is one of the most-used ebook formats. On mobile devices like Android tablets or smartphones, you can open an EPUB file using Play Books or your favorite ebook readers. Alternatively, you can also read an EPUB file by converting it to a format recognized by your ebook reader app (you need to convert your EPUB file MOBI on Kindle devices).
If you want to read an EPUB file on desktop (Windows 10) and have no idea about the app you should use, there the top list you can consider.
