It uses XHTML to construct the content of a book. The latest version ePub3 which is published on 11th Oct ’11 promises better support for multimedia and more languages like Chinese, Arabic etc to make it more of an international standard. Most of the fiction comes in ePub format of size less than 1MB; on an average it has the least footprint for an eBook.
ePub format was initially supported by Sony eBook readers and recently became the most popular format due to the huge popularity of iPad. Its iBooks eBook Apps use ePub as the native format. For more information visit http://idpf.org
Mobi format is very popular since it is the basis of Kindle ASW format. It was originally an extension of the PalmDOC format by adding certain HTML like tags to the data. Many MOBI formatted documents still use this form. However there is also a high compression version of this file format that compresses data to a larger degree in a proprietary manner. The higher compression mode is using a huffman coding scheme that has been called the Huff/cdic algorithm. For more information visit
