MP4 to MP3 Converter

Extract the audio from a video as an MP3 file.

Questions

Is my video uploaded to a server?
No. The conversion runs entirely in your browser using your device's own video engine. Your file never leaves your computer.
What bitrate is the MP3?
192 kbps, which is transparent for most listening. The audio is decoded from your file and re-encoded to MP3 in your browser.
My video has no sound, why did it fail?
There has to be an audio track to extract. Screen recordings made without audio won't produce an MP3.
