Free EPUB structure scan
Upload an EPUB that failed KDP or EPUBCheck.
The scan checks one reflowable EPUB for structure errors, then offers a repaired EPUB beta only when a deterministic fix passes revalidation.
- 1. Choose .epub
- 2. Run scan
- 3. Read report or download repair
What the report includes
See a sample report- whether the file passes the basic EPUB container and package checks
- which OPF, nav, NCX, manifest, spine, link, or media item is affected
- whether each issue is repairable, needs manual review, or is outside V1A scope
- whether a repaired EPUB beta download is available after EPUBCheck revalidation
- what to do next for each issue and a copyable report summary
Upload privacy
Your EPUB is temporary scan input.
- Uploaded EPUB files are temporary scan input and expire after 24 hours.
- You can delete the uploaded file from the result page.
- The report shows paths and error summaries, not manuscript text.
- EPUB files are not used to train models.
Before upload
Make sure this is the right kind of file.
- Use a reflowable EPUB 2 or EPUB 3 file exported from your writing or formatting tool.
- Upload the EPUB package itself, not a DOCX, PDF, KPF, KCB, ZIP export, or Kindle Previewer log.
- Keep the file at 30 MB or smaller and upload only one EPUB at a time.
- Do not upload fixed-layout books, comics, picture books, DRM-protected files, or image-first EPUBs.
- EPUB Fixer does not handle KDP account, tax, payment, review, listing, category, or pricing issues.
Not supported:
DOCX/PDF conversion, fixed-layout EPUB repair, DRM removal, comics, image-first books, cover design, typography, book formatting, and KDP account or listing issues.
