Merge Audio Files
Combine multiple audio files into one track, in the order you choose — free and processed entirely in your browser.
About Merge Audio Files
Combining voice memos, podcast segments, or several songs into one continuous file usually means opening a full audio editor for a simple task. This tool merges multiple audio files into one, in whatever order you arrange them.
Files at different sample rates or channel counts are automatically normalized so they play back correctly joined together, and the result is encoded to a standard MP3. Everything runs locally in your browser.

Frequently Asked Questions
Can I merge files with different formats or sample rates?
Yes — files are automatically normalized to a consistent sample rate and channel count before merging, so mismatched sources join together cleanly.
Is there a limit on how many files I can merge?
No hard limit, but very long combined audio takes longer since everything runs on your own device's processing power.
Can I add a crossfade between tracks?
Not currently — tracks are joined end-to-end without a transition effect. A dedicated audio editor would be the better tool if you need that specific effect.
Is my audio uploaded anywhere?
No. Merging and encoding both happen entirely in your browser.
