EPUB Fixer

About

EPUB Fixer assists independent authors in identifying issues within EPUB files that are rejected by KDP, Kindle Previewer, or EPUBCheck. By uploading a single reflowable EPUB, users can view the specific impacted paths. The service distinguishes between problems that can be automatically corrected and those requiring manual attention. A repaired file is available for download only after it successfully passes another EPUBCheck review. All scanning is free and requires no registration, with uploaded files being removed within one day.
