Save the sound from any video as an MP3. Drop in an MP4, MOV, WebM, or M4V and Solmi decodes the audio track in your browser and re-encodes it as MP3. Use it for a live performance you filmed, a voice note recorded as video, a podcast episode published as video, or a lecture you want on your phone.
Drop the video onto the converter, choose an MP3 quality, and press Convert. Your browser decodes the audio track, Solmi encodes it as MP3, and the file downloads on the page.
MP4, MOV, and M4V work in every major browser. WebM works in Chrome, Edge, and Firefox. MKV and AVI are not decoded by browsers, so remux those to MP4 first with any free desktop tool.
This tool converts files you already have on your device. It does not download from YouTube or other sites. If you own the video, download it from your own account first and drop the file here.
There is no upload, so the only work is decoding and encoding. A five-minute video takes a few seconds on a laptop; an hour-long recording takes about a minute.
Slightly, because MP3 is lossy. At 192 kbps and above the loss is not audible in normal listening. For music, pick 320 kbps.
No. The converter runs entirely in your browser: your file is decoded and re-encoded on your own device, and nothing is sent to a server. That is also why it is fast — there is no upload wait and no download wait, just the conversion itself.
Yes, completely free with no signup, no file-size paywall, and no watermark. Once your audio is converted, you can turn the track into a music video with Solmi's AI music video generator — also free to start.
