MP4 to MP3
Pull the soundtrack out of a MP4 file and save it as a clean MP3. The universal H.264 video format — and sometimes you just want the audio. This runs entirely in your browser, so the file never leaves your device.

Is the MP4 to MP3 converter free?
Yes — it's completely free, with no sign-up, no watermark, and no limit on how many files you convert.

How do I extract the audio from MP4 files as MP3?
Drop your MP4 file into the tool above, then click the convert button. The MP3 file is generated locally and ready to download in moments.
Does the MP3 keep the original audio quality?
Yes — the audio track is extracted and encoded to a high-quality MP3, with no re-recording or generational loss beyond the encode itself.
Does this work on mobile?
Yes — it runs in any modern browser on desktop or mobile, with nothing to install.
