EPUB to M4B, with real chapter marks
M4B is the audiobook format players understand best: one file that remembers where you stopped and lets you jump between chapters. Pagetape writes the chapters from your EPUB's table of contents straight into the M4B.
Your file is read in this browser. Only the chapters you choose are sent to us, and only when you convert.
How to do it
- 01Drop your EPUB below and check the chapter list.

- The file is AAC audio in an MP4 container with the M4B brand, the book cover embedded, and title and author tags filled in.
- Books longer than about 15 hours come as several M4B files (Part 1 of 3 and so on), each with its own chapters.
- One price per book: $1.99 up to 4 hours of audio, $3.99 up to 12 hours, $5.99 up to 24, $8.99 up to 48.
Questions
- Will the chapters show in my player?
- Yes, in players that read MP4 chapter marks: Audiobookshelf, BookPlayer, Smart AudioBook Player, Apple Books on Mac and VLC, among others.
- What bitrate is the audio?
- About 48 kbps mono AAC, which is plenty for one speaking voice and keeps a 10-hour book near 220 MB.
- Is there a size limit for the EPUB?
- The limit is the length of the text: up to 48 hours of audio per book. Images in the EPUB do not count.
