EPUB Fixer - Find EPUB errors and verify safe repairs before KDP upload

EPUB Fixer helps indie authors diagnose EPUB files that fail KDP, Kindle Previewer, or EPUBCheck. Upload one reflowable EPUB to see the exact affected paths, separate issues with a deterministic repair from those needing manual review, and download a repaired copy only after it passes EPUBCheck again. Scans are free, no signup is required, and uploaded files are deleted after 24 hours.

I've changed my pricing model 4 times in 12 months. Not because

I wanted to. Because the market kept telling me I was wrong and

I kept not listening fast enough.
