Combine MP3s into a Single M4B
The best way to enjoy an audiobook is as a single, organized file. Merging your MP3s into the M4B format does exactly that. An M4B file functions like a professional audiobook: it supports chapter markers for easy navigation and remembers your playback position, keeping everything tidy. Our tool makes it simple by automatically turning your filenames into a chapter list.
