Split Audible audiobooks by chapter
A 20-hour audiobook in a single MP3 is painful on devices that can't remember your position or jump between chapters. AudiblePort can split each book into one file per chapter, automatically.

Each book gets its own folder with numbered chapter files, ready for any player.
When per-chapter files make sense
Chapter files are the best choice for simple MP3 players, car stereos and any player that treats audio as a list of tracks. Every chapter becomes its own track, so skipping forward or back is one button press.
- Basic MP3 players and USB car stereos
- Sharing a single chapter for study or language learning
- Players without resume or chapter support
When to keep a single file
If your player supports chapters (Apple Books, BookPlayer, Audiobookshelf, Smart AudioBook Player…), a single M4B with chapter markers is cleaner: one file per book, with navigation built in.
Frequently asked questions
Are chapter files numbered in order?
Yes, so they play in the right order on any device that sorts by name.
Can I split into MP3 and M4B?
Yes, chapter splitting works with both output formats.
Does splitting affect audio quality?
No more than converting to the chosen format and bitrate does.
