Repairs broken EPUB/MOBI covers, encoding glitches and metadata online, no install.

Listed Sep 21, 2026

Fixes what converters and old scanners leave broken in ebook files: a cover that won't show on Kindle (usually stray EXIF data), garbled text from a wrong-encoding conversion, or an author sorted under the wrong letter. Runs in the browser on EPUB, AZW3, MOBI, FB2 and PDF (PDF is converted to EPUB first), up to 50MB, with no account and the file deleted after an hour. A lighter Telegram bot handles title, author and cover changes, but cover repair and text correction stay on the website only.

What holds up

  • +Fixes 9 separate known causes of a missing Kindle cover — not a single blind retry.
  • +No account, no install — drop a file in the browser and it's deleted after 1 hour.
  • +Handles EPUB, AZW3, MOBI, FB2 and PDF, converting PDF to EPUB automatically.
  • +Shows each garbled-text fix in its original sentence before you approve it, not a silent auto-correct.

Mind the limits

  • −Cover repair and text fixes are web-only — the Telegram bot only converts formats and covers.
  • −50MB file-size cap, so heavily scanned image-based ebooks may not fit.
