Frequently Asked Questions
What is FB2 format?
FB2 (FictionBook 2) is an XML-based e-book format popular in Russian-language reading apps and e-book libraries.
What PDFs convert best to FB2?
Text-based PDFs with selectable text work best. Scanned PDFs may need OCR before conversion.
Will the output be reflowable?
Yes. FB2 is designed for reflowable reading, so the text adapts to the screen instead of preserving rigid PDF page geometry.
What file size is supported?
Up to 500 MB per file.
Why choose FB2 instead of PDF?
FB2 is easier to read on e-book apps because the font size and layout can adapt to the device screen.
