Frequently asked questions
How faithful is the FB2 result?
Text converts reliably, since
FB2 is a single UTF-8 XML document and HTMLZ is zipped HTML. Images are re-embedded as base64 inside the FB2 file. FB2's styling model is deliberately simple, so rich formatting is reduced to basic structure.Why convert HTMLZ to FB2?
FB2 is an open, DRM-free format popular for fiction and widely supported by e-reading apps. It packs an entire book into one portable XML file with embedded images.Where does FB2 open?
FB2 is read by many e-book applications on desktop and mobile. It is not natively supported on Kindle, so reaching that device means converting FB2 onward to another format first.What is lost going to FB2?
FB2 is oriented around flowing text (chapters, paragraphs, emphasis), so complex HTML tables, multi-column layouts and elaborate CSS from the source do not map cleanly. Expect the document to be flattened into a clean reading structure.
