EPUB Fixer

Finds EPUB errors before your next KDP upload, free to scan

Webfreemiumglobal

A web app that scans reflowable EPUB 2 and EPUB 3 files to diagnose validation errors reported by KDP, Kindle Previewer, or EPUBCheck, listing affected internal file paths and indicating whether each issue has an automatic repair, needs manual review, or is outside scope. It is intended for indie authors self-publishing on KDP. Scans are free with no signup, uploaded files are deleted after 24 hours, and a repaired EPUB is provided only after it passes EPUBCheck.
