About extracting audio
This tool extracts the audio from a video and saves it as MP3, WAV or M4A. It uses ffmpeg compiled to WebAssembly and runs entirely in your browser, so your video is never uploaded. There is no watermark and no sign-up.
How Extract Audio from Video works

How it works
The tool discards the video stream and saves the audio, encoding it to your chosen format — MP3 (small), WAV (lossless) or M4A/AAC. Everything runs locally with ffmpeg in WebAssembly; the engine downloads once (~32 MB) and is then cached.
Common uses
Pull a song or voice track out of a recording, save a podcast clip, or grab the audio from a lecture or interview.
