FB2 (FictionBook 2) is the e-book format of the Russian-speaking world and many indie e-reader apps: a single XML file with strict semantic markup — sections, titles, epigraphs, poems. Readers like FBReader and older PocketBooks prefer it.
Typical use: Convert FB2 to EPUB when your reader (Kindle, Kobo, Apple Books) does not speak FictionBook, or to TXT/HTML for plain reading and archiving.
About the FB2 format
FB2 (FictionBook 2) stores a whole book as one strictly-structured XML file: <section> for chapters, <title>, <epigraph>, <poem>, even <table>. That semantic rigour — not just styled text — is why FBReader, AlReader and older PocketBook devices favour it, and why conversions out of FB2 preserve the chapter tree cleanly.
Its weakness is reach: mainstream ecosystems (Kindle, Kobo, Apple Books, Google Play Books) do not accept it. Converting to EPUB moves the book into every modern reader; TXT/HTML covers plain reading, note-taking and long-term archiving.
