FictionBook (FB2) is an XML-based ebook format designed for fiction. It uses semantic tags for structure (chapters, sections, epigraphs, poems) and stores images as base64-encoded data within the XML. It is particularly popular in Russia and Eastern European countries.
The conversion uses Calibre, the leading open-source ebook management tool. Calibre fully supports FB2's XML structure and can reliably extract all text content including nested sections and special elements.
Yes. FB2's special structural elements like poems, epigraphs, and citations are extracted as text. Line breaks within poems are preserved in the plain text output.
The output uses UTF-8 encoding, which fully supports Cyrillic, Latin, and all Unicode characters. Russian, Ukrainian, Bulgarian, and other language content is preserved accurately.
Images (stored as base64 in FB2) are removed. The annotation (book description) text is included, but binary image data is stripped.
Yes. Calibre converts FB2's section/title hierarchy into plain text with clear chapter separators, maintaining the book's organizational structure.
