Upub

Upub turns fixed PDF pages—including scanned pages—into reflowable EPUB text that adapts to the font size you choose. Instead of shrinking an entire PDF page to fit your screen (which often leads to tiny type, sideways scrolling, and lost reading position), upub rebuilds the book so words wrap naturally like a real ebook.

More than character extraction, upub analyzes page layout and reconstructs reading order and book structure. It rebuilds chapters, headings, images, and footnotes, and is designed to remove repeating elements like headers and page numbers from the reading flow. This helps your ebook read like a book rather than a page-by-page capture.

For scanned PDFs (where the content is page images), upub uses AI-assisted OCR to recover readable text. Pages that can’t be verified confidently are flagged in a downloadable, page-level quality report so you can spot what may need review.

Choose how you’ll read the result: upub packages output as EPUB 3 and supports reader profiles for common devices and apps, with conversion plans available as one-time page-credit packs (credits never expire). You can also create a typographic cover from the title/author, upload your own artwork, or generate an AI background cover during conversion.

What does “reflowable EPUB” mean in Upub’s conversion?

Your PDF text is rebuilt so it wraps to your screen at the font size you choose. That avoids the fixed-page behavior that causes zooming, panning, and lost position.

Can Upub convert scanned PDFs (image-based pages)?

Yes. Upub uses AI-assisted OCR plus layout analysis to recover readable text from page images. Pages that can’t be verified confidently are listed in a downloadable quality report.

Will headers, page numbers, and columns show up in the EPUB text?

Upub is designed to remove repeating headers and page numbers from the reading flow and rebuild the correct reading order. Complex pages may still require review, and uncertain pages are highlighted in the quality report.

Does Upub rebuild chapters, headings, images, and footnotes?

Yes. Upub rebuilds reading order and book structure, including chapters, headings, images, and footnotes, so the EPUB reads as a book rather than a screenshot of pages.

Where can I read the converted EPUB?

You can read the resulting EPUB 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 do my credits expire?

There’s no subscription and credits never expire. You purchase one-time page-credit packs and use them when you’re ready to convert.
