Frequently asked questions
How do I combine songs into one file?
Add the tracks, drag them into order, choose a gap or crossfade, then join and download a single MP3 or WAV.
Can I add a crossfade between tracks?
Yes. Set a crossfade so each track blends into the next, or a gap for silence between them.
Can I join files with different formats?
Yes. Every file is decoded to the same sample rate before joining.
Are my files uploaded to a server?
No. Audio Joiner runs entirely in your browser, so your files stay on your device. Nothing is uploaded, stored or seen by anyone else.
Is Audio Joiner free?
Yes. It is completely free, with no sign-up and no watermarks.
