How to use Mute video
- 1
Drop the video
Add one MP4, MOV, WebM, MKV or AVI file of up to 500 MB and 10 minutes. Its length, resolution and audio codec appear under the player.
- 2
Choose what happens to the sound
Remove takes the audio track out completely, Lower turns it down to a level between 0 and 95%, and Mute a part silences only the stretch you mark.
- 3
Check it in the player
The preview follows your choice: it plays silently, at the lower level, or goes quiet between the two times you set with the playhead buttons.
- 4
Save the new file
Press the button and download name-muted.mp4 (or -quieter, -muted-part); the container stays the same as the original whenever it can.
Limits and Pro
One video at a time, up to 500 MB and 10 minutes long, with no watermark.
Pro handles files of up to 4 GB and up to 10 hours long. See Pro
About Mute video
Mute video gives you a copy of a clip with the sound changed and the picture left exactly as it was. Removing the audio is a remux: the video stream's packets are copied into a new file without the audio track, so a 10-minute 1080p recording is done in seconds and loses nothing. Lowering the volume or silencing a section has to re-encode the sound, but only the sound: the tool decodes it, multiplies the samples by the level you chose (with a 12-millisecond fade at the edges of a muted part so it doesn't click) and encodes it again as AAC for MP4 and MOV, Opus for WebM and MP3 for AVI, at 160 kbps.
Typical uses are a screen recording with keyboard noise, a phone video with wind or a stranger's conversation, a clip with copyrighted music that a platform would block, or a background loop for a website that must autoplay silently. Setting the level to 0% instead of removing the track keeps a silent audio stream, which some apps and editors expect.
The tool handles the first video and audio track; extra language tracks and embedded subtitles are left out of the new file. It cannot separate a voice from music, cut the picture, or add a new soundtrack: it only removes, lowers or silences what is there.
Privacy
The video is read from your disk and rewritten in this browser tab, by mediabunny with your browser's WebCodecs audio encoder or by ffmpeg.wasm in a Web Worker. No part of the file is uploaded or stored; the 31 MB ffmpeg engine is downloaded from jsDelivr only if your browser needs it.
Features
Lossless removal
Taking the sound out copies the picture as it is, so even long videos finish in seconds.
Turn it down
Set any level from 0 to 95% and hear it in the preview before saving.
Silence one stretch
Mark a start and end with the playhead and only that part goes quiet.
Same format back
MP4, MOV, WebM, MKV and AVI files keep their container.
