Frequently asked questions
How do I join audio files?
Add at least two files in the order you want, then run Join. Matching codecs can copy streams quickly; otherwise files are re-encoded.
Are my files uploaded?
No. Joining runs on your device via WebAssembly. Audio never leaves your browser.
Is Join Audio free?
Yes. Free with no limits or watermarks, because processing runs on your own device.
