Upub

Upub turns fixed PDF pages—including scans—into reflowable EPUB text you can actually read. Instead of shrinking a page to fit your screen, it rebuilds the book so text wraps naturally at the font size you choose, without sideways scrolling or losing your place.

More than extraction, upub analyzes page layout and rebuilds reading order, chapters, headings, images, and footnotes. It also removes repeating headers and page numbers from the reading flow to keep the content focused on the book itself.

Scanned PDFs are handled with AI-assisted OCR. Every page is assessed with a confidence score, and pages that can’t be verified confidently are flagged in a downloadable quality report, so you’re not left guessing. Upub supports multiple input formats and outputs validated EPUB 3 for many reader devices using selectable reader profiles.

What does “reflowable EPUB” mean in practice?

Your text is rebuilt so it wraps to the screen at the font size you choose, instead of keeping the PDF’s fixed page layout.

Can upub convert scanned PDFs?

Yes. For PDFs that contain page images, upub uses AI-assisted OCR to recover readable text and produces a downloadable quality report when pages can’t be verified confidently.

Will headers, page numbers, or layout artifacts end up in the EPUB text?

Upub is designed to remove repeating headers and page numbers from the reading flow. Complex pages may still require review, and the quality report highlights uncertain pages.

Does upub rebuild the book structure (like chapters, headings, and footnotes)?

Yes. It rebuilds reading order and book structure, including chapters, headings, images, and footnotes, so the EPUB reads like a book rather than a page-by-page capture.

Where can I read the resulting EPUB?

You can read with common EPUB apps and devices, including Kindle via Send to Kindle, plus Kobo, Apple Books, PocketBook, Onyx Boox, and reMarkable.

Is there a subscription or an expiry date for credits?

No. You purchase page-credit packs once, and credits never expire.
