Help & Answers

Frequently Asked Questions

Can I read converted FB2 files on e-readers like PocketBook?
Yes. FB2 is a premier e-book format supported natively by PocketBook, FBReader, Moon+ Reader, and many popular e-ink devices.
Why does text extraction fail on scanned PDFs?
Scanned PDFs consist of full-page photos rather than selectable text glyphs. Scanned documents must be processed with OCR software before text can be extracted into an e-book.
Is my unpublished manuscript or book safe from disclosure?
Yes. All parsing and FB2 XML compilation take place entirely within your local browser memory. No data is sent to external servers.
