よくある質問
Quick answers.
›Which EPUB versions are supported?
The tool validates both EPUB 2 and EPUB 3 standards, checking for version-specific requirements in the `content.opf` and navigation files.
›Is my manuscript private?
Yes. The validation logic runs locally in your browser so the file stays on your machine and is never transmitted to our infrastructure.
›What does a 'manifest mismatch' error mean?
This occurs when a file exists inside the EPUB archive but is not listed in the `content.opf` manifest, or vice versa.
›Can it fix the errors automatically?
No, this is a diagnostic tool designed to identify structural issues. You will need to use an e-book editor to apply the recommended fixes to your source file.
