MOBI is a Mobipocket eBook file definitely designed for e-Readers or mobile devices. We often need to convert MOBI to EPUB, because:

  • EPUB is much better compatible with complex typography, charts, formulas, etc. than the MOBI.
  • EPUB is popularly used for most devices and e-Readers, like iPhone, Adobe Digital Editions, iTouch, iRiver Story HD, Nook, Sony Reader, Kobo Vox, etc., but MOBI is not.
  • EPUB is an open standard, so there will be more choices in development tools, such as Calibre, Sigil, and Jutoh. They enable users to self-produce ePub eBooks.

When you’re ready to convert Kindle e-books to EPUB on Mac, Windows or mobile, find an e-book converter. Here are top 8 MOBI to ePub converters for you to check out.

MOBI Format

Both MOBI and AZW are amazon’s official eBook formats. Their growth depends in large part on the popularity of Amazon (a huge content provider), and its Kindle e-book reader.

MOBI is an older format, and AZW is just another form of MOBI. You can say, AZW adds a protective shell to MOBI, and Amazon uses it to lock e-books with DRM.

Most of the MOBI files come from two sources: converted from EPUB, PDF, TXT files or come out from Amazon store. The latter are either officially produced by Amazon, or published by authors through KDP (Kindle Direct Publishing, which empowers authors to bypass the publishers and release e-books directly on Amazon.)
