EPUB vs MOBI: Definitions, Pros and Cons
Crystal Chen updated on Jan 03, 2023 to PDF Knowledge Center | min read
Deciding between EPUB vs. MOBI is not something casual digital book readers ever worry about. To this set of people, an e-book is an e-book, and either works just as well.
However, if you are a purist reader or a publisher, the format usually matters. EPUB and MOBI are two of the three most popular formats for publishing digital books. While you can enjoy virtually any e-book in either format, they both have their differences, advantages, and drawbacks.
I'll tell you this straight away: compared one to the other, EPUB comes away as the winner. That said, there are situations where either format outshines the other. After you're done reading, you will understand their differences and know which works best for you.
EPUB vs. PDF: Which One is Better for You
Portable Document Format, usually called PDF, is a file format that contains text, images, embedded fonts, hyperlinks, videos, interactive buttons, forms, and many more.
What Is EPUB?
Many consider the EPUB the industry standard, and for many good reasons. It is the most widely accepted format by readers. It also supports more devices than any other e-book format.
EPUB is short for electronic publication. The file is layout agnostic, which means that a reader can enjoy content on any device without worrying about the screen size affecting its formatting. It allows tweaks in font type and size, highlighting, bookmarking, and the embedding of images.
You can open an EPUB file on a Kobo, Barnes & Noble Nook, and most desktop and mobile e-book readers like Calibre. Until very recently, you could not directly open it on an Amazon Kindle.
What Is MOBI?
MOBI is another e-book file format that is now phasing out. Developed by Mobipocket, Amazon purchased it in 2005. As the largest digital bookseller in the world, it was not considered out of place for the retail giant to use a file format exclusively for e-books on Kindle devices.
The company discontinued official support for MOBI in 2011, replacing the format on Kindle with AZW3, KFX, and KF8. All three successors are based on MOBI but come with different DRM schemes.
