During the time, this type of file format became one of the most popular e-book formats in the world. Because of that, EPUB is industry standard, and it is compatible with almost every e-reader device and app. Some of the most famous ones are Apple iBooks, Adobe Digital Editions, Aldiko for Android, Google Play, Kobo, etc.

Due to its popularity, it’s no wonder that almost 50% of all our e-book file conversions, as a result, have EPUB file format. Files are often converted from MOBI to EPUB, AZW to EPUB, TCR to EPUB, and PDF to EPUB but also EPUB to MOBI, and EPUB to PDF.

What is a MOBI file?

MOBI is short for Mobipocket, and it is a famous e-book file format. It is originally developed as Amazon’s exclusive e-book file format for all its Kindle devices.

This type of file format has the famous DRM protection which makes it perfect for all authors and writers. It means that an e-book file is locked, and you can’t read it unless you are an owner of a Kindle device associated with the Amazon account that purchased the previously mentioned e-book.

However, the MOBI file format has one downside and its lack of compatibility. That’s why our users often ask MOBI to EPUB or MOBI to PDF converters to help them with it.


The main difference between these formats is that EPUB is a widely supported and vendor-independent file format. However, when it comes to Kindle devices, MOBI is the favorite one. After all, MOBI is an Amazon-exclusive file format. But that is not the only difference between them.

If you want a file that accommodates graphics and multimedia better, you should choose EPUB over MOBI. But if you have an e-book with plain text that doesn’t require much space, your choice should be MOBI file format. It means that the MOBI file can be easily opened even on low-end reading devices.
