Merge Audio Files
Combine multiple audio files into a single MP3, in the order you choose. Reorder the list, then merge — all locally in your browser, nothing uploaded.

What this tool does
It concatenates several audio files end to end into one continuous MP3, re-encoding so that clips with different sample rates or codecs join without gaps.
Order matters
Files play in the order shown. Use the up and down arrows to arrange them exactly how you want before merging.
Privacy
Merging happens entirely in your browser with ffmpeg.wasm — your files never leave your device.
How to merge audio
- Drop two or more audio files into the zone above.
- Reorder them with the arrows, or remove any you don't need.
- Press Merge, then download the combined MP3.
