MP4 to MP3
Save the sound from a video as an MP3, for a recording of a talk, a voice note filmed on a phone, or music from your own videos. The video stays on your device.

How to use it
- Choose the MP3 quality; 192 kbps suits most uses.
- Choose your videos, or drag them onto the box.
- Download each MP3, or all of them as a ZIP file.
Which quality should I pick?
128 kbps is fine for speech and keeps files small. 192 kbps is good for music and most other uses. 320 kbps is the highest MP3 quality. An MP3 at 192 kbps takes about 1.4 MB for every minute of sound, so a four-minute recording comes to roughly 5.8 MB.
Choosing a higher quality than the video's own sound cannot improve it; it only makes the file larger.
Which videos work?
MP4 and WebM videos work in current browsers. MOV files from iPhones usually work too, depending on how the phone recorded them. MKV, AVI and WMV files are not supported yet.
Only use videos you have the right to
This page converts files that are already on your device. It does not download videos from websites, and it should only be used for recordings you own or have permission to use.
Questions
How long a video can I convert?
Videos up to about an hour are comfortable on a computer. Longer videos need a lot of memory while they are being converted, and a phone may run out sooner.
Are my files uploaded?
No. The work happens inside your web browser, on your own device. Before your file is opened, this page locks itself: from then on your browser refuses to let it fetch, upload or send anything at all. You can check: once the page has loaded, switch off your internet connection and it will still work. How the lock works.
