What This Tool Fixes
Apple Books (iBooks) modifies EPUB files when you import them. The content stays intact, but Apple changes the internal packaging structure — specifically how the ZIP archive wraps the book.
This breaks compatibility with:
- Amazon Kindle — Send to Kindle rejects the file
- Calibre — reports the file as a folder, not an ebook
- Kobo e-readers — file won't open
- Other EPUB readers that follow the EPUB specification
EPUB Fixer repackages the file with the correct structure so readers that rejected the Apple Books packaging can open it. The fix takes seconds and leaves the book content unchanged.
Important: DRM-Protected Books
This tool fixes EPUB packaging issues — not DRM. If you purchased a book from the Apple Books Store, it's protected by Apple's FairPlay DRM and cannot be opened on other e-readers.
EPUB Fixer works with DRM-free EPUBs:
- Books you imported into Apple Books from other sources
- DRM-free purchases from publishers
- Library books (OverDrive, Libby)
- Free ebooks (Project Gutenberg, Standard Ebooks, etc.)
How to tell: If you bought the book directly from the Apple Books Store, it almost certainly has DRM. If you imported it from another source, it's likely DRM-free.
Frequently Asked Questions
Why doesn't my Apple Books EPUB work on Kindle?
Apple Books modifies the EPUB file packaging when you import books. This changes the internal ZIP structure in a way that Kindle and other e-readers don't accept. The book content is fine — only the wrapper is broken. EPUB Fixer repairs this packaging instantly.
Can I transfer Apple Books to Kindle?
Yes, if the book is DRM-free. Export the EPUB from Apple Books, fix it with EPUB Fixer, then send it to your Kindle using Amazon's Send to Kindle service or email it to your Kindle address. If the book was purchased from the Apple Books Store (with DRM), it can only be read in Apple Books.
Does this work with Kobo and other e-readers?
EPUB Fixer repairs the Apple Books packaging issue that can cause Kindle, Kobo, Calibre, and other readers to reject an otherwise usable EPUB.
Is my file safe?
Your file is processed on our server and deleted immediately after the fixed version is generated. We don't store, read, or analyze your books. No account required, no tracking.
What's the maximum file size?
500 MB. Most EPUBs are well under this limit.
Why is there a 60-second rate limit?
To keep the service free and fast for everyone. One conversion per minute per user prevents server overload.
What if the fix doesn't work?
The book may use DRM, or it may have validation, metadata, table-of-contents, formatting, or publishing-platform issues that this packaging repair does not address.
