PDF to EPUB
Reconstruct selected PDF text into semantic EPUB 3 chapters with a navigation document, package metadata, headings, paragraphs, lists, and confidently detected tables. Integrated local OCR can include scans, while the compatibility report calls out reflow and image limitations.

Fidelity mode: Semantic reflow creates searchable XHTML chapters and navigation. Fixed PDF page appearance, graphics, and uncertain reading order are not disguised as a clean ebook.

Frequently asked questions
▸Will each ebook page match the PDF page?
No. EPUB is intentionally reflowable, so pagination changes with reader size and typography. Source page grouping controls chapters, not fixed screens.
▸Does it include a table of contents?
Yes. A standards-based EPUB navigation document links every generated chapter.
▸What content may be missing?
Decorative vectors, embedded fonts, complex image placement, forms, and interactive PDF content are omitted and reported. Review converted equations and unusual reading orders.
