FAQ

Is this tool free?

Yes — no sign-up, no installation, completely free to use right away.

What is this tool?

The video → MP3 converter pulls the sound out of MP4, MOV, WEBM, MKV, AVI and M4V videos and saves it as an MP3. You can set the bitrate (128/192/256/320 kbps), sample rate, mono/stereo, volume normalization and a time range, plus fade in/out and ID3 tags (title, artist, album). Queue several files and they convert one by one, ready to download individually or as a single ZIP. Conversion runs on the ffmpeg engine inside your browser, so files are never uploaded. The engine (~30 MB) is fetched once on your first conversion.

Are my uploaded files sent to a server?

No. Everything runs only on your own computer, inside your browser, and your files are never sent to a server or anywhere else. So you can use it with complete peace of mind, without worrying about your file contents leaking.
