MOBI eBook Format MOBI Converter
The MOBI ebook format was developed by the French company Mobipocket in 2000. MOBI files were intended to be used on mobile phones, computers and personal digital assistants (PDAs), which were popular in the 1990s and early 2000s before the arrival of smartphones. Unlike EPUB files, MOBI files were protected by Digital Rights Management, making it harder for the contents to be copied and shared.
Amazon bought Mobipocket in 2005. The company retired the MOBI format and support for it in 2016 after developing the AZW and AZW3 formats for the Kindle. However, you can still read MOBI files on Kindle devices and with the Calibre ebook application. You can also get specific MOBI-reader software. If you use an ereader that doesn’t recognise MOBI files, you may need to use a tool like Zamzar to convert them into another format like EPUB.
EPUB eBook Format EPUB Converter
EPUB is the standard open-source format for ebooks. EPUB is short for ‘electronic publication’. The format was developed in the mid-late 2000s by the International Digital Publishing Forum and is an alternative to formats like AZW, developed for the Kindle. EPUB files can be viewed on a wide range of e-readers and digital reading apps, including NOOK, Apple Books, Okular and Calibre. Amazon announced in 2022 that new Kindle models would also support EPUB files.
The EPUB standard is now maintained by a World Wide Web Consortium (W3C) working group. The EPUB format comprises three open standards – one defining content markup, one describing the ebook structure, and one packaging all the files into a compressed format. EPUB files normally include an index page for navigation, and accessibility features to adjust text size or allow for text-to-speech. EPUB also has the potential to include interactivity, accessible image, video, or audio elements.
