Change channels and sample rate

Some devices, games and platforms need mono audio or a specific sample rate. Mono halves the data of stereo audio, and a lower sample rate makes the file smaller, at some cost to the highest tones.

Questions

What happens to a stereo file when I choose mono?

The left and right channels are averaged into one. Sounds that were only on one side are kept, but quieter.

Is my audio uploaded?

No. The conversion runs in your browser.
