About Video to MP3

Pull the audio out of a video and save it as an MP3. Drop in an MP4, MOV, WebM, MKV, or AVI and we extract and encode the soundtrack with ffmpeg.wasm at the bitrate you choose — perfect for lectures, interviews, and music videos.

The extraction happens entirely in your browser. Your video file stays on your device, so nothing is uploaded to convert it.
