Why Traditional PDF to EPUB Converters Break
PDF is a print-oriented fixed layout format without semantic document flow. Conventional tools like Calibre read text horizontally across the page, causing dual-column papers to scramble together, captions to slice sentences in half, and footnotes to get stranded as broken body text.
- ✕Horizontal scanning causes dual columns to interleave into gibberish.
- ✕Footnotes, page numbers, and running headers cut right through sentences.
- ✕Table of contents keeps printed dots (. . . . .) and dead page numbers.
- ✕Produces XML syntax errors that crash Apple Books and Kindle.
- Spatial column projection disentangles academic columns into clean flow.
- Footnotes are automatically bound into native tap-to-popup <aside> tags.
- Interactive <nav class="inbook-toc"> replaces printed dots with clean links.
- 100% W3C EPUBCheck 4.2.6 verified: 0 Errors, 0 Warnings.

Frequently Asked Questions
Can I convert complex two-column arXiv or IEEE papers?
Yes. Our engine uses geometric spatial column projections to analyze left and right blocks independently, ensuring reading flow moves down the left column first, then to the right column, without cross-column bleeding.
How are footnotes handled in the generated EPUB?
Footnotes are extracted from page footers, isolated from body text, and mapped with semantic epub:type="noteref" and epub:type="footnote" attributes. On modern e-readers like Apple Books, tapping the footnote number displays an instant popup without losing your reading position.
Is my uploaded PDF document secure and private?
Yes. Your documents are streamed purely in-memory through our high-performance typesetter without permanent disk persistence or AI model training. Once the EPUB stream is downloaded, the memory buffer is wiped.
