Format description
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 Even though it was originally made for the Mobipocker Reader for PDAs (now defunct), it is supported by other e-book readers.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.
Common questions about converting to MOBI
