MP4 to MP3
Pull the soundtrack, podcast or music out of a video and save it as an MP3. Everything runs in your browser via ffmpeg.wasm — nothing is uploaded.
Última atualização: July 2026
MP4 to MP3 extracts the audio track from a video and saves it as an MP3 file. Choose a video, pick a quality (128–320 kbps), and the tool re-encodes just the audio using FFmpeg compiled to WebAssembly — entirely in your browser, so the video is never uploaded. The engine downloads once on first use, then is cached.
Como usar MP4 to MP3
- Choose a video file (MP4, MOV, WebM, etc.).
- Pick an MP3 quality (192 kbps is a good default).
- Click Extract, then download the MP3.
Perguntas frequentes
Is my video uploaded?
No — the audio is extracted locally in your browser via ffmpeg.wasm. Only the engine binary is downloaded (once).
Why is the first run slower?
The FFmpeg engine (~32 MB) loads on first use, then it's cached for the rest of your session.
What video formats work?
Most common ones — MP4, MOV, WebM, MKV and more — as long as they contain an audio track.
