What this does

Fast MP3 uses server-side FFmpeg on the live site. Local WebM works without a server but runs in real time. WAV output is uncompressed and can be much larger than MP3.

How to use

Choose a file and tune the compressor.

Choose Fast MP3 on the live website for quick compression. Lower bitrate means a smaller file. Use local WebM when testing without the server, and choose WAV only if you need an uncompressed edit copy.
