Will the EPUB look exactly like the PDF?

No. PDF uses fixed pages while EPUB reflows text for different screens. Chapter text is preserved where extraction or OCR succeeds, but precise layout changes.

Can I edit chapter names?

Yes. Review the detected page boundaries, rename chapter titles, and exclude unwanted chapters before export.

Does it support scanned PDFs?

The established extraction pipeline can use OCR fallback for scanned pages. OCR quality depends on scan clarity and should be reviewed.

Is the output a valid EPUB package?

The exporter creates the EPUB mimetype, container, package OPF, navigation document, and XHTML chapters, then reopens and checks them before download.
