About the formats

Mime type application/x-mobipocket-ebook

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 Even though it was originally made for the Mobipocker Reader for PDAs (now defunct), it is supported by other e-book readers.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.
Extension azw3

Developed by Amazon
Mime type application/vnd.amazon.mobi8-ebook

Description

Amazon's AZW3 e-book format is a successor to AZW for handling e-books on Kindle devices. Its newer features include support for more modern web standards, such as HTML5 and CSS3, allowing for better styling. Note that some AZW3 files are DRM-protected, meaning that MConverter is unable to process them.
