How this works in your browser
The tool instructs the engine to ignore the audio stream and copy the video stream verbatim into a new container. Because the picture data is never decoded, no encoder runs at all, which is why this is among the fastest operations on the site regardless of how long the clip is. The output keeps the original container and codec, so an MP4 remains an MP4 playing exactly as before, minus a track. It is worth being clear that the audio is omitted rather than silenced: no silent stream is written, so the sound is not recoverable from the output file. All of it runs through FFmpeg compiled to WebAssembly inside your browser tab.

Frequently asked questions
Does this affect video quality?
No. Only the audio stream is removed; the video stream is copied as-is with no re-encoding.
Can I add different audio afterwards?
This tool only removes audio. You would need a separate video editor to add a new soundtrack.
Which video formats are supported?
MP4, MOV, MKV, WEBM and AVI are all supported as input.
Is the audio really gone, or just silenced?
Genuinely gone. The audio stream is not written into the output file at all, so there is nothing to recover by turning a volume slider back up. That matters when the reason for muting is a background conversation or something private caught on the recording.
Why is this so much faster than compressing?
Because nothing is re-encoded. The picture data is copied across untouched and the audio is simply omitted, so the work is essentially rewriting the file rather than rebuilding it. Even a long video finishes quickly.
Can I keep a copy of the audio?
Yes, run the video through one of the extract audio tools first to save the soundtrack as a separate file, then mute the video. The two tools together give you the picture and the sound as independent files.
Is my video uploaded anywhere?
No. The audio track is dropped inside your browser tab.
