MP4, MOV, WebM, MKV… Files over ~500 MB may exceed browser memory.
Extract audio from video without uploading
This tool uses FFmpeg compiled to WebAssembly to pull the soundtrack out of any video and save it as MP3, M4A or WAV. Everything happens on your computer, so even private recordings stay private.
Why is the first conversion slower?
The video engine (~30 MB) is downloaded once and then cached by your browser for future use.
