MP4 to MP3 Converter
Extract the audio from a MP4 video as a MP3 file.
To convert MP4 to MP3, upload the video and the audio track is extracted and encoded as MP3. MP3 is lossy and universally supported. It is the safe choice when the file has to open somewhere you cannot control. Everything runs in your browser through FFmpeg compiled to WebAssembly, so the video is never uploaded.

MP3 is lossy and universally supported. It is the safe choice when the file has to open somewhere you cannot control. Extracting audio from video is a re-encode, not a copy, so the result is bounded by the quality already in the source — a 96 kbps track exported at 320 kbps gains nothing but file size.
