Merge M4A files

Upload M4A files, arrange them in the order you want, and combine them into a single M4A file.

How M4A files are merged

Add two or more M4A files and arrange them in the order you want. The tool combines them into one M4A file containing AAC-LC audio encoded at a target bitrate of 192 kbps.

Everything is processed in your browser, so your audio files are not uploaded to a server.

Common reasons to merge M4A files

Combine exported Voice Memos, audiobook chapters, podcast segments, lecture recordings, or other audio saved as separate M4A files.
