Both formats, briefly
HTMLZIN
HTMLZ is a book packed as ordinary web files: the HTML holding the text, a stylesheet, and the images, zipped together into one archive. Nothing sits behind a proprietary container, so this is the format to pick when you want to edit a book by hand, feed it to your own publishing script, or inspect how the markup came out of an earlier conversion. Calibre reads and writes it, which makes it a comfortable stopping point between two other formats. Choose HTMLZ when the file is a working copy rather than the version someone will read.
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.
