EPUB Fix – Repair & Recover

Fix broken EPUBs in seconds. Repairs mimetype errors, missing metadata, and invalid structure — exports a clean, Apple Books-ready file. Simple, fast and reliable.

EPUB Fix repairs the internal structure and metadata of EPUB files that fail to open, display incorrectly, or are rejected by reading apps.

Many EPUB issues are not caused by corrupted data — they stem from malformed structure, a missing or incorrect mimetype declaration, or incomplete metadata such as a missing language tag. EPUB Fix targets exactly these problems and silently corrects them in seconds.

What it fixes

Incorrect or missing mimetype Missing dc:language metadata in the OPF file ZIP structure that does not conform to the EPUB specification

What it cannot fix

EPUB Fixer repairs structural and metadata issues only. It cannot recover files that are genuinely corrupted or physically damaged, and it does not remove or bypass DRM (Digital Rights Management) protection. DRM-protected EPUBs must be managed through the platform or store they were purchased from.

How to use

Tap "Open EPUB File", select your file, and EPUB Fix will analyse and repair it automatically. Share or save the fixed file directly to Apple Books or Files.
