Introduction Mobipocket SA is a French company incorporated in March 2000 that created the .mobi e-book file format and produces the Mobipocket Reader software for mobile phones, personal digital assistants (PDA) and desktop operating systems. Kindle devices are designed to use Amazon's own e-book formats: AZW. In late 2011, the Kindle Fire introduced "Kindle Format 8" (KF8), also known as AZW3 file format. AZW3 supports a subset of HTML5 and CSS3 features, while acting as a container for a backwards-compatible MOBI content document.
Technical details The Mobipocket e-book 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 basically 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. Similarly to 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.
