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.

FB2 eBook Format

FB2 Converter

The FB2 format name stands for FictionBook 2.0. It’s a type of ebook file mostly used for literature like novels or short stories. FictionBook is a Russian company, and it introduced the FB2 format in the 2000s. The format itself comprises one XML file, which describes the structure of the book, rather than the appearance. This means that sections that are highlighted with bold or italics will display consistently, but the exact appearance of the book might vary on different devices or ereading apps. An FB2 file will also contain metadata like the author, publisher, and edition release date.

FictionBook has since introduced the FB3 format, although FB2 is more popular. FB2 files can be opened by many ereaders, including Calibre, PocketBook, BeBook, CoolReader, KyBook, Geometer Plus FBReader, and even OpenOffice. FB2 files will also open in some browsers with an ereader extension.
