How to Extract MP3 Audio from Video

Click the upload area or drop an MP4, MOV, WebM or other video.

The video track is discarded and the sound is encoded as high-quality MP3 in your browser.

Save an audio file that's a fraction of the video's size.

✓High-quality MP3 output (~190 kbps VBR)

✓Files typically 90%+ smaller than the video

✓Works with MP4, MOV, WebM and more

✓100% local — recordings stay private

What MP3 quality do I get?+

The audio is encoded at high VBR quality (~190 kbps equivalent) — indistinguishable from the source for speech and most music.

How much smaller is the MP3 than the video?+

Typically 90%+ smaller, since the video track is by far the largest part of the file. An hour-long lecture video becomes a compact podcast-sized MP3.

What are common uses?+

Turning lectures and meetings into listenable audio, saving music from your own recordings, and preparing podcast material from video interviews.

Is my video uploaded?+

No — the extraction runs entirely in your browser. Personal recordings and meeting captures never leave your device.
