Features

Six output formats: MP3, WAV, FLAC, AAC, Opus and M4A cover every common use case.
Configurable bitrate lets you balance file size and audio quality.
Estimated output file size is shown before conversion so you know what to expect.

How it works

Drop an audio file — MP3, WAV, FLAC, AAC, Opus or M4A — to load it.
Select the target format and optionally adjust the output bitrate.
Click Convert and FFmpeg WebAssembly transcodes the audio, then download the result.

Your files never leave this page

Every conversion runs entirely in your browser using WebAssembly. There is no upload, no server-side processing, no analytics, and no cookies. Open DevTools → Network during the operation and you will see zero outbound traffic.
