Why Convert FB2 to EPUB
EPUB is supported by Apple Books, Kobo, Nook, Google Play Books, and nearly every eReader except Kindle. It's the global open standard for ebooks.
EPUB text reflows to fit any screen size — from phone to tablet to dedicated eReader. Readers control font size, margins, and line spacing.
EPUB 3 supports embedded fonts, SVG images, MathML equations, audio/video, and advanced CSS styling for beautiful ebook layouts.
EPUB is maintained by W3C as an open standard (ISO/IEC 23736). Your books are never locked to a single vendor or platform.
EPUB uses ZIP compression internally, making files significantly smaller than equivalent PDF versions — important for eReaders with limited storage.
EPUB 3 has native accessibility features: semantic markup, text-to-speech support, and screen reader compatibility for visually impaired readers.

About the FB2 Format
FB2 (FictionBook 2.0) is an XML-based ebook format created in Russia that has become the dominant standard for digital books in Russia, Ukraine, and across Eastern Europe. Unlike formats that store visual presentation, FB2 uses semantic markup to describe the logical structure of a book — title pages, chapters, sections, epigraphs, poems, and citations are all encoded as distinct XML elements, making it exceptionally well-suited for fiction and literary works.
FB2 stores rich metadata including author biography, genre classification, series information, and cover images directly within the XML structure, making library management and cataloging straightforward. The format handles Cyrillic and Unicode text natively, ensuring proper rendering of Russian, Ukrainian, Bulgarian, and other scripts. FB2 is supported by popular reading apps like FBReader, CoolReader, and Moon+ Reader, particularly on Android. While less common outside Eastern Europe, FB2 files can be converted to EPUB, PDF, or MOBI for use on international eReaders and Kindle devices.
