About Extract Audio

Rip the audio out of a video and save it as a standalone MP3. Drop in an MP4, MOV, WebM, or MKV and ffmpeg.wasm extracts and encodes the soundtrack at the bitrate you choose — perfect for turning a lecture, interview, or music video into an audio file.

The extraction runs entirely in your browser with no upload and no signup, and it works offline. Your video stays on your device the whole time.
