Mute Video

Strip the audio track and keep the picture exactly as it was. Runs entirely in your browser.

Copying, not re-encoding

A video file is a container holding separate streams: one for picture, one or more for sound, sometimes subtitles. Removing the sound means writing out a new container with the video stream copied across unchanged and the audio simply left behind. Nothing is decoded, nothing is compressed again, and no pixel changes.

That is why this finishes in seconds on a file that would take minutes to convert. It is also why the result is not merely “visually identical” but actually identical — the same encoded frames, in a new wrapper.

The reason this belongs on your own machine

Most conversion tools are about convenience. This one is usually about the opposite: people mute a clip because the audio contains something that should not travel with it. A colleague talking in the background of a screen recording. A child’s name. Music that would get the upload taken down.

Uploading that file to a web service to have the audio removed hands over the exact thing you were trying not to share, and trusts a policy page that it will be deleted afterwards. Here the file is opened, rewritten and handed back without leaving the tab, so there is no policy to trust.

Muting is not redaction of the picture

Worth being precise: this removes sound and nothing else. Anything visible in the frames — a name on screen, a reflection, a notification banner — is still there afterwards, because the video stream is untouched. If the thing to remove is in the picture, this is not the tool.

Mute Video FAQ

Is my video uploaded to remove its sound?

No. The file is remuxed by code running on your own device. This matters more here than almost anywhere else on the site: if you are muting a clip before sharing it, the audio usually contains something you specifically do not want other people to have — a conversation in the background, a name, an address. Sending that recording to a stranger's server to have it removed is exactly the wrong move.

Does the picture lose any quality?

None at all. The video stream is copied across byte for byte rather than decoded and re-encoded, so the output is pixel-identical to the input. Only the audio track is dropped. That is also why this is one of the few video tools here that stays fast on a large file — there is no encoding to do.

How long does it take?

Seconds, even for a file measured in gigabytes, because nothing is being re-encoded. If you find a tool that takes several minutes to mute a video, it is re-encoding the picture unnecessarily and quietly degrading it in the process.

What if the video has no sound to begin with?

It passes through and you get a valid file back. There is no error and nothing to undo — the instruction is simply 'do not include audio', which is satisfied whether or not there was any.

Can I lower the volume instead of removing it?

Not here. Changing the volume means decoding and re-encoding the audio, which is a different operation with a different cost, and this page is built around the fact that copying is free. Muting is all-or-nothing by design.
