Handles any mix of files

Free and private
All processing happens locally with the Web Audio API — your files never leave your browser, there’s no signup, and the WAV export has no watermark. Need to trim a file before joining? Use the Audio Cutter first.
Frequently asked questions
How many files can I join?
As many as you like, as long as they fit in your browser’s memory. Very long combined files take a little longer to render.
Can I reorder the files?
Yes — use the up and down arrows next to each file to set the play order before exporting.
Do the files need to be the same format?
No. Different formats, sample rates and channel counts are matched automatically. The export is a WAV.
Does it upload my audio?
No. Everything runs in your browser; your files never leave your device.
Is it really free?
Completely — no signup, no watermark and no limits.
