How it works
- Pick an MP4, MOV, WebM or other video from your device.
- To extract audio from video, the tool finds the sound track inside the file and leaves the picture out.
- It decodes that sound and encodes it as MP3 at the bitrate you chose. The default is 192 kbps.
- If the video has no sound track, the tool stops and shows a clear error.
- Download the MP3 file.

Questions
How do I get MP3 audio from an MP4 video?
Pick the MP4 on this page and press Convert to MP3. The sound is taken from the video and saved as an MP3 file you can download.
Does converting MP4 to MP3 lose quality?
Often a little. The sound is decoded and encoded again as MP3, which adds some loss. Choosing 320 kbps keeps the most detail, and the default is 192 kbps.
What happens if my video has no sound?
The tool shows a clear error instead of making an MP3, because there is no sound track to convert.
Is my video uploaded when I convert it?
No. Your browser reads the video and creates the MP3, so the file stays on your phone or computer.
