EPUB → M4B

Convert an EPUB to an M4B audiobook

Drop your EPUB, pick a narrator and download one M4B with chapters and cover. It plays in Apple Books, your audiobook app and the car, offline.

What you get

•
One .m4b file for the whole book, not a folder of tracks.
•
Chapter marks taken from the book’s own table of contents.
•
The cover, title and author, so it shelves itself in your audiobook app.
•
Your choice of size: compact for the phone, or higher quality for good headphones.

5.
Download it and play it in Apple Books, your audiobook app, the car or anywhere else, offline.

Why M4B

M4B is the audiobook format. Apple Books and dedicated audiobook apps show its chapters and cover and remember your place in it. Need a file that plays on literally anything? Take MP3 instead.

Chapters that match the book

Your EPUB already knows its chapters, so the M4B does too. Title, author and cover come from the file. In the Editor you see every chapter and leave out the ones you don’t want in the audio, like the copyright page or the index.

Hear it before you make it

Every English book is free to listen to with Standard voices, on every plan. Play a chapter or the whole thing, try a few narrators and choose your chapters, then make the file.
Rather just listen? The book stays in your library and plays on the web, iPhone and iPad, and Mac (Windows coming soon), with read-along text, a sleep timer and your place synced.

Questions people ask

Will the M4B work in Apple Books?

Yes. Choose one of the M4B sizes, add the file to Books on your Mac or iPhone, and it shows up as an audiobook with its chapters and cover.

Can I make an M4B of a book in another language?

Yes. Books in other languages are narrated with Premium voices, which use your plan’s Premium hours. English books can also be narrated free with Standard voices.

How long does the file take?

It depends on the length of the book. You can listen while it builds, or close the page: we email you when it’s ready.

Which EPUBs work?

Any DRM-free EPUB or KEPUB up to 10 MB. Store purchases locked with DRM can’t be opened.

Is it free?

Yes, in English. Standard voices are unlimited on every plan, Free included. Free also gives you 10 minutes of Premium voices, one book of your own and one audiobook download. Listener includes 3 downloads, Premium 15 and Ultra unlimited, along with more books and Premium hours.
