Mute video online — free, private, no upload
Remove the audio track from an MP4, MOV, WebM or MKV file entirely locally in your browser using WebCodecs — the video is read, muted and muxed on your device and never leaves it. Muting is a lossless copy, so the video stream itself is untouched.
How it works
- Drop a video file. It stays on your device the whole time.
- Preview it, then press Mute video.
- The video stream is copied through losslessly — no re-encode, no wait on a slow video encoder — while the audio track is dropped.
- Preview the muted result and download it.
Frequently asked questions
Does muting re-encode my video or lose quality?
No. Muting is a lossless fast path — the video stream is copied through untouched, only the audio track is dropped. There's no re-encoding, so there's no quality loss and no extra time waiting on a video encoder.
Is my video uploaded anywhere?
No. The entire process runs locally in your browser using WebCodecs and mediabunny — your video is read, demuxed and re-muxed on your device and never leaves it.
What video formats does it accept, and what do I get back?
Drop an MP4, MOV, WebM or MKV file. The output is always an MP4 container with the same video stream and no audio track.
Can I get the audio back after muting?
No — downloading creates a brand-new muted file, and your original file on disk is never touched, so you can always start over from it if you need the audio again.
Why would I want to remove the audio from a video?
Common reasons: stripping background music before adding your own audio or captions, removing a sensitive conversation before sharing a clip, or preparing a silent looping background video for a website.
Why does my browser say it isn't supported?
This tool needs WebCodecs, which current Chrome, Edge and Firefox on desktop or Android provide. Every browser on iPhone and iPad shares Apple's WebKit engine, which doesn't expose a working encoder yet, so the muter is unavailable there.
