MOBI


 * This article is about the e-book format. For the top-level domain, see TLD .mobi.

MOBI format was originally an extension of the PalmDOC format by adding certain HTML-like tags to the data. http://wiki.mobileread.com/wiki/MOBI

The Amazon Kindle used to use this format, in a variation called AZW or AZW3, but later switched to the more standardized EPUB format.

File extensions
.mobi is the standard file extension for this format, but .prc is used instead in Palm OS, where only a limited range of extensions are supported.

This format has no connection to the .mobi top-level domain, intended for use on sites targeted at mobile devices.

Identification
