HOE FB2
IS ONTSTAAN.

FictionBook (FB2) is the Russian-speaking world’s answer to EPUB. Created in 2004 by Dmitry Gribov and a community of Russian developers and librarians, FB2 is an XML-based ebook format explicitly designed for fiction: one file holds the entire book as pure semantic markup (sections, paragraphs, italics, poems), with no CSS or visual styling. Readers apply their own typography, which makes FB2 refreshingly simple and radically portable.

FB2 became the dominant format of the largest Russian ebook sites (Flibusta, Lib.rus.ec, LitRes) and the preferred input for Russian e-readers (PocketBook, ONYX). Outside the Russian-speaking world FB2 is rare, but the format is technically superior to MOBI for text-only books — XML structure means perfect text extraction, search, and reflow on any screen.

WEETJES &
TRIVIA.

FB2 is essentially "EPUB without CSS" — semantic XML only, no visual styling.

The format dominates Russian-language ebook distribution through sites like Flibusta and LitRes.

FB2 files can contain Base64-encoded cover images and illustrations inline — no external assets.

The spec is maintained by a grassroots community, not a standards body — and has remained backward-compatible for 20 years.

PocketBook e-readers, popular in Eastern Europe, default to FB2 rather than EPUB.

STERKE PUNTEN &
BEPERKINGEN.

Sterke punten

Pure XML — trivial to parse, search, and transform.
Single-file ebooks with inline images.
Excellent on low-powered e-readers.
De-facto standard in Russian-language ebook ecosystem.
Simple structure makes conversion to any other format straightforward.

Beperkingen

No styling, no custom fonts, no fixed layouts.
Minimal Western-language tooling.
Kindle and Apple Books do not support FB2 natively.
Non-fiction with complex typography (textbooks, cookbooks) is a poor fit.
