uPub
Converts fixed PDF pages, even scans, into reflowable EPUB text for Kindle or Kobo.
upub turns a fixed PDF page, including scanned pages, into a reflowable EPUB by rebuilding reading order, chapters, headings, footnotes and images instead of just extracting characters like a basic converter. For scans it uses AI-assisted OCR and layout analysis, then flags any page it couldn't verify confidently in a downloadable quality report. Pricing is pay-per-use: 1,000 pages from $4.99, one payment, and credits never expire.
What holds up
- +Flags low-confidence OCR pages in a downloadable quality report instead of silently guessing.
- +Credits never expire and there's no subscription — pay once, 1,000 pages from $4.99.
- +Rebuilds chapters, headings, footnotes and reading order, not just raw characters like basic converters.
- +Lets you add or replace a cover on an existing EPUB without reconverting the whole book.
Mind the limits
- −Calibre converts PDFs for free; upub charges per page in exchange for the reading-order rebuild.
- −Scans rely on AI OCR — the quality report admits some pages still can't be verified confidently.
