Common questions
Are my files uploaded anywhere?
No. Joining happens inside your browser. Your audio stays on your device and is never sent to a server.
Can I join files of different formats?
Yes. You can mix MP3, WAV, M4A, OGG and FLAC. Everything is converted to the same sample rate and saved in the format you pick.
What does crossfade do?
The end of each file fades out while the next one fades in over two seconds, so songs flow into each other without a gap.
Is Join Audio free?
Yes, completely free, with no sign-up and no watermark.
