Open an iBooks Author book in Pages on Mac
You can open an iBooks Author file in Pages, then export your book from Pages to EPUB format, and publish it directly from Pages to Apple Books. Pages creates a document from your iBooks Author file and includes all of the page templates (both used and unused) from the iBooks Author template. iBooks Author books made from reflowable templates are converted to word-processing documents in Pages and books made from fixed layout templates are converted to page layout documents.
Not all iBooks Author features are supported by Pages, so your imported book may look different from the original. If your book includes unsupported features such as certain widgets or a cover in a different orientation than the rest of the book, that content is saved in a separate folder for your reference.
For more information about working with your iBooks Author book in Pages, see this Apple Support article.
