This runs entirely in your browser using a WebAssembly build of FFmpeg — your audio file is never uploaded anywhere. The first conversion needs to download the conversion engine (~30MB) once; after that it's cached for the rest of your session.

The first time, your browser downloads the conversion engine itself (about 30MB). Every conversion after that in the same session is faster since it's already loaded.
320 kbps is close to the source quality, 192 kbps is a solid everyday balance, and 128 kbps gives you the smallest file size for quick sharing.
