Both formats, briefly
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.
FB2OUT
FB2, short for FictionBook, keeps a whole book inside one XML file: chapters, paragraphs, footnotes, cover art and the metadata describing them. The structure is marked up rather than laid out, so software can re-render or convert the book without guessing where a chapter begins. The format is common in Russian-language catalogues and is handled by a long list of desktop and mobile readers. Convert to FB2 when the library or app you are feeding asks for it, and away from FB2 when the book needs to land on a Kindle or Kobo.
