MOBIIN
MOBI is the format Amazon built its early Kindle library on, after buying it from Mobipocket. Books in it keep bookmarks, highlights and your place in the text, and Kindle hardware from that era reads them directly. Newer Kindles moved on to AZW3, so MOBI now matters mainly when an older device or a reading app of the same vintage is still in service. If you inherited a shelf of .mobi files, converting them to EPUB or AZW3 keeps those books readable on current hardware.
AZW3OUT
AZW3, also called Kindle Format 8, is what Amazon uses on current Kindle devices and apps. Next to MOBI it understands HTML5 and CSS3 markup, embedded fonts and more deliberate page layouts, so drop caps, tables and styled headings survive the trip instead of flattening out. Choose AZW3 when a book is going onto a Kindle and you care how the page looks, not just that the words arrived. Finished files carry the .azw3 extension and sideload over USB or by sending them to your device.
