What is MOBI file?

A MOBI file is a digital ebook created in the Mobipocket format. This file format was developed by a French software company and was later acquired by Amazon.com. A MOBI file may include DRM protection, which prevents the eBook from being copied or printed. The file may include other features such as bookmarks, notes, and highlights.

MOBI files can be read on various devices, including smartphones, tablets, and e-readers. They can also be read on Amazon's Kindle devices and apps.

More information

Amazon's new Kindle Format 8 (KF8) is built on the MOBI standard and adds support for additional features such as fixed layouts, embedded fonts, and more. Amazon now owns the MOBI format, which many eBook formats use, including AZW, AZW1, and AZW3. These formats also include a DRM scheme that makes them proprietary to Amazon.

NOTE: Mobipocket eBooks also use the same extension as Kindle books.
