Extract audio from video

One tool for pulling sound out of almost any video file — MP4, MOV, WebM, MKV, OGV, or AVI all work the same way here. Point it at your video and get back the audio track on its own, whether that’s a soundtrack you want to sample, a voice memo buried in a screen recording, or a lecture you want to listen to without the visuals.
The whole extraction happens on your own device through WebAssembly, so whatever is in the video — including anything private or unreleased — never leaves your browser tab to get processed.

How it works
- Upload almost any video file (MP4, MOV, WebM, MKV, OGV, or AVI).
- Wait while your browser extracts the audio track locally.
- Download the extracted audio file.

Frequently asked questions
Which video formats does this accept?
MP4, MOV, WebM, MKV, OGV, and AVI are all supported — this is our general-purpose audio extractor for whatever video format you happen to have.
Is the video uploaded to pull out the audio?
No. Extraction runs entirely client-side via WebAssembly — the video file stays on your device from start to finish, and there is no server step involved.
What size can I process, and do I need a specific browser?
Up to 300MB on desktop (100MB on mobile), with no duration limit since only audio is extracted. It works in any modern browser with WebAssembly support — WebCodecs is not required for this tool.
