MP4 to MP3, answered.

How do I convert MP4 to MP3? +

Upload the MP4 above; Vocce strips the video stream and encodes the audio track as MP3 at your chosen quality. Multi-hour files are fine — they're processed in a queue, not in your browser tab.

Does video quality matter for the MP3? +

No — only the audio track matters. A 4K video and a 480p video with the same audio produce identical MP3s.

Can I pick the audio quality? +

Yes — high (320kbps), medium, and low presets, or let the default match the source quality.

What about other video formats? +

MOV, MKV, WebM, AVI and more all work — see the Extract Audio from Video tool for the full list.
