Studio / Summer 2026 batch
EPUB structural repair
Bring an existing EPUB and its validation errors. Receive a supported structural repair, a check report and a record of what stayed unchanged.
What you get
A broken package or navigation reference can stop a finished book from importing. You need a readable explanation and a corrected file, without a rewrite of your manuscript.
- Your original EPUB and a separately repaired copy
- Whole-file validation results, including warnings
- A record of the structural changes made
- Text and media preservation checks
What you bring
- An existing DRM-free, reflowable EPUB you may share
- The full validator or importer error message
- Your intended platform and publication deadline
- Confirmation of the reading order you expect
Out of scope. We assess supported structural errors before accepting an order. Rewriting, fixed-layout books, DRM removal, accessibility certification and guaranteed retailer acceptance are excluded.
