Join Audio Files Online for Free
Join several audio files into one continuous track. Upload your clips, drag them into the order you want, and the tool merges them end to end — one after another, with no gap. You can combine different formats (for example an MP3, a WAV and an OGG), and the result downloads as a single MP3. No sign-up and no watermarks.
How to Join Audio

- On the next screen, drag the files into the order you want, and set each track's volume if needed.
- Optionally add a crossfade between tracks, then click merge and download your combined MP3.
