EPUB is one of the most widely used ebook formats. EPUB is an open, XML-based standard for distributing digital books and other publications.
Note: Nowadays, commercially sold ebooks often have DRM protection which prevents them from being opened or converted by third party software.

Mime type application/x-mobipocket-ebook


MOBI is a Mobipocket e-book file. Even though it was originally made for the Mobipocker Reader for PDAs (now defunct), it is supported by other e-book readers. MOBI is specifically designed for low-bandwidth mobile devices. In addition to storing the contents of digital books, MOBI files may include bookmarks and DRM protection. The latter prevents creating unauthorized copies of the book and acts as copyright protection.
