Audio Merger
Add two or more audio files, arrange them into the order you want, and merge them into one continuous track — processed entirely in your browser.
Audio Tools Runs entirely in your browser
Your audio file is processed on your device and is never uploaded to our servers.
Only use this tool with files you own or have the right to process.
Drag audio files here or choose them
You can add more than one file — they'll be merged in list order
What this tool does
Joins several audio files into one in the order you arrange them, with a choice of output format.
When to use it
- A recording that came out as several parts and should be one file.
- Assembling audiobook chapters into one continuous file.
- Adding an audio intro or outro to a main recording.
- Collecting short clips into a single file for distribution.
How to use it
- Put your audio files on the drop area or choose them — they merge in list order.
- Order them with "Move up" and "Move down".
- Choose the "Output file format".
- Click "Merge files", then "Download merged file".
A practical example
Input
Four ten-minute audio files in sequence.
Output
One forty-minute file running through all four without gaps.
Limitations
- The merge button stays disabled until you add at least two files.
- Unsupported files are skipped with a notice saying so.
- There are no crossfades between files; the merge is a straight join — add fades afterwards with the Audio Fade tool if you want them.
- Files with different sample rates are normalised during the merge.
Privacy and processing
All the files you queue are joined on your device, and none of them is uploaded.
Technical notes
- The join is performed locally by FFmpeg.wasm, which also handles the output format you picked.
