Cut songs. Blend them into one mix.

Load your tracks, mark the part of each you want, match loudness and crossfade the joins. Everything runs in your browser, so your audio stays on your device.

How it works

1. Add songs

Drop your files in. They are decoded on your device.

2. Cut and arrange

Drag the handles to choose each part, then set the order.

3. Blend and export

Match loudness, set a crossfade, compare A and B, then download MP3 or WAV.

Seamless transitions

The transition assistant checks silence at each end, compares loudness, estimates tempo and suggests a crossfade. It enables tempo matching only when the estimate looks reliable, and every change can be previewed against the original cuts. No tool can guarantee an invisible join, so you stay in control.

Supported formats

Import MP3, WAV, OGG, M4A, AAC and other formats your browser can decode. Export MP3 or WAV.

Popular tools

Audio Splitter

Frequently asked questions

Is my audio uploaded?

No. Editing happens in your browser. Only the MP3 encoder library is downloaded the first time you export MP3.

Do I need an account?

No. Add songs, edit and download without signing up.

Which formats can I use?

Import: whatever your browser can decode, usually MP3, WAV, OGG, M4A and AAC. Export: MP3 or WAV.

Will every merge sound seamless?

Not always. The tools help, and you can compare with the original cuts before exporting.
