How to Merge Audio Online? Concatenate Multiple Tracks
Explains how to join multiple audio files in order, plus the privacy benefits of fully in-browser processing.
Audio merging places multiple clips end-to-end in the order you choose, producing one continuous file.
This tool uses FFmpeg (WebAssembly) in your browser, so the audio is never uploaded to a server.
Same-format tracks prefer stream copy; mixed formats are re-encoded then joined.
Conversion runs entirely locally. Download the result before closing the tab — refreshing clears temp files.
