Drop a video on the box above. The tool reads it, shows a player and fills in the full length as the part to convert. To keep only part of the sound, play the video to the point you want and press Use current time under Start or End, or type the times as minutes and seconds. Pick a quality and press Convert to MP3.
Which quality to pick
| Bitrate | Size per minute | Good for |
|---|---|---|
| 128 kbps | about 0.96 MB | Talks, lectures, podcasts and voice notes |
| 192 kbps | about 1.44 MB | Music for phones and earbuds; the default |
| 320 kbps | about 2.4 MB | Music from a high quality source played on good speakers |
A higher bitrate can't add detail that the video's sound never had. Most phone and web videos store their sound as AAC at 128 to 256 kbps, so converting that to 320 kbps MP3 gives a bigger file that sounds the same as 192. Mono sound stays mono.
Formats it opens
MP4, MOV (including iPhone videos), WebM and MKV files open in most browsers. The tool only needs to read the sound, so a video whose picture your browser can't play can usually still be converted. If the file has no sound track, or its sound is in a format the browser can't decode, the tool says so before it starts.
Browsers have no MP3 encoder of their own, so the page loads a small open source encoder the first time you convert. Everything runs in your browser tab, and the video is never uploaded, which also means there is no upload wait for large files.
Where the video comes from
For a video you have the rights to that is online, the YouTube Video Downloader and Instagram Video Downloader save the video first, and this tool takes it from there. Only convert music and videos you own or have permission to use.
Other video tools
To make the video itself smaller rather than taking the sound out, use Compress Video. To turn a few seconds of it into a looping animation, use Video to GIF.
