Information about MOBI and AZW file formats

Full name MOBI - Mobipocket AZW - Kindle Format 8
File extension .mobi, .prc .azw,.azw3,.azw4
MIME type application/x-mobipocket-ebook application/vnd.-amazon.-mobi8-ebook
Developed by Mobipocket SA
Type of format Ebook file format Ebook file format
Description The MOBI file extension was created in 2000 by Mobipocket. This company produced Mobipocket Reader applications for computers and smartphones. In 2005, Amazon bought Mobipocket. As a result, MOBI files are identical to Amazon's AZW format for Kindle devices. Kindle devices are designed to use Amazon's ebook format: AZW. In late 2011, the Kindle Fire introduced "Kindle Format 8" (KF8), also known as the AZW3 file format. AZW3 supports a subset of HTML5 and CSS3 features while acting as a container for a backward-compatible MOBI content document.
Technical details The Mobipocket ebook format is based on the Open eBook standard using XHTML and can include JavaScript and frames. It also supports native SQL queries to be used with embedded databases. The Amazon Kindle's AZW format is just the Mobipocket format with a slightly different serial number scheme, and .prc publications can be read directly on the Kindle. The Kindle AZW format also lacks some Mobipocket features such as JavaScript. Kindles do not support the EPUB file format used by many other e-book readers. Like EPUB, Amazon's file formats are intended for reflowable, richly formatted e-book content and support DRM restrictions, but unlike EPUB, they are proprietary formats.
