Mute Video Online
Remove the sound from any video instantly using lossless container remuxing. Everything runs locally on your device - no upload, no quality loss, no watermark.
Use this tool when the audio is not worth saving. If your clip has wind, traffic, camera handling noise, a private conversation or music you cannot use, muting the whole track gives you a clean video file you can share or rebuild.
This is different from audio repair. If you need to keep a voice and remove only music, hiss or a single background sound, you are asking for audio separation, not simple muting. GrepCut Mute Video removes the entire audio track so the result is silent from start to finish.
For standard MP4 or MOV files that already use H.264 or H.265 video, GrepCut drops the audio track and copies the video stream. That means the visible frames stay untouched, so muting is fast and loss-free for the video track.
If your file uses a format that needs a compatibility export, such as WebM with VP9 or AV1 video, GrepCut converts it to a standard H.264 MP4. That takes longer because the browser has to encode a new video file.
GrepCut runs the mute operation in your browser. Your video does not need to be uploaded to a server just to remove the audio track.
That local workflow is useful when your clip includes faces, client footage, internal recordings or anything you would rather not send to a third-party service. You still get a normal MP4 export that is ready to share.
Can you mute a video without losing quality?
Yes, when your video can be remuxed. For MP4 or MOV files with H.264 or H.265 video, GrepCut removes the audio track and keeps the video stream as-is. If your file needs transcoding, the export is converted to a standard H.264 MP4.
Will your video be uploaded?
No. The file is processed locally in your browser, so your video stays on your device.
Can you remove music but keep voices?
Not with this quick mute tool. If music, voices and background sounds are mixed into the same audio track, muting removes all of them. To keep dialogue, you need audio separation or a full editing workflow.
Can you mute only part of a video?
This tool removes all audio from the clip. If you need to mute a specific section, lower one noisy moment or replace the sound, open the video in [GrepCut Studio](/).
What video formats can you mute?
You can mute common video files such as MP4, MOV, WebM and MKV. H.264 and H.265 video can usually be copied without re-encoding, while WebM, VP9 or AV1 sources may be transcoded to H.264 MP4.
Why is your WebM export taking longer?
WebM files often use VP9 or AV1 video. GrepCut may convert those videos to H.264 MP4 for compatibility, so the browser has to encode a new file instead of only dropping the audio track.
Will the muted video be smaller?
Usually, removing the audio track reduces some file data. The final size still depends on your original format and whether the video track can be copied or needs to be transcoded.
Can you add new music after muting?
Yes. Download the silent MP4 for another editor, or open it in [GrepCut Studio](/) to add a new music bed, voiceover, captions or trims.
