Use the free Video Muter Online below: remove the audio track from any MP4 or WebM video and keep the picture. Your file never leaves your device.
Keep the picture, drop the sound
Some videos look right and sound wrong. A phone clip picks up wind, traffic, or a private conversation in the background. A screen recording carries a notification ping halfway through. The Video Muter Online above fixes all of these the same way: it saves a new copy of your video with the picture untouched and the audio track removed completely.
Everything happens in your browser. Your video is never uploaded to a server, and you do not need an account or an install. The file stays on your device, the muted copy downloads straight to your downloads folder, and your original file is never changed.
How to mute a video
First, choose your video file. MP4 and WebM work in most browsers. MOV works too, but only if your browser can play it, so if a MOV file refuses to load, that is a browser limit, not a broken tool. Once the video loads, the page shows its length and file size, and a preview player appears.
Next, press the remove-audio button. There are no settings to tune and no track to pick: the tool records the whole video again, picture only, with no audio track at all. Because it re-records in real time, processing takes about as long as the video itself. A 30-second clip takes roughly 30 seconds to build.
When it finishes, the result area shows a preview player with the muted clip, the before and after lengths and sizes, and a plain sentence saying the copy plays silent. Watch it before you download, and turn your own volume up for a second: silence here is the proof the tool worked. Then download the muted copy, or mute another file.
Worked example: a six-second clip, muted for real
Here is a real run through the tool, checked file by file. The test clip was 6.0 seconds long and 86.3 KB, with a picture track and a sound track. We pressed the remove-audio button and let the tool record the whole clip again, picture only.
The result was a new video about 6.1 seconds long and about 294 KB, saved as MP4 in Chrome. Opening the output file and listing its tracks showed one video track and no audio track at all. That check is the whole point of this tool: the muted copy does not merely play quietly, it has no sound track left inside it. Note also that the file got bigger even though sound was removed. The tool re-encodes the picture at a fixed quality setting, and a busy test picture compresses worse than the calm original, so size follows the picture, not the presence of sound.
Good uses for a muted video
The most common use is cleaning up a clip before sharing it. A birthday video with a private conversation in the background becomes safe to send once the sound is gone. A shop tour with traffic noise becomes a quiet clip you can put your own voice or captions over later.
Muted clips also work as silent background video on a page or a display, where sound would annoy people anyway. Shops, classrooms and waiting rooms often loop video with no sound at all. And creators sometimes mute first, then add a fresh voice track in their editor, because cutting the old sound out cleanly beats trying to talk over it.
Honest limitations
Muting here is permanent for the new copy. The muted file has no audio track to turn back on, so keep your original file if you might want the sound again later. The tool never overwrites the original, but once you delete it, the sound is gone for good.
The output is re-encoded, not a copy of the original file with one track deleted. The tool plays your video and records the picture again, so the picture passes through a fresh round of compression. On a normal phone or screen video you will not notice the difference, but do not mute the same clip over and over from a muted copy. Always work from the original.
The output format depends on your browser, and the tool tells you the format before you start. Chrome, Edge and recent Safari save MP4. Firefox saves WebM, because Firefox cannot record MP4. WebM plays fine in Chrome, Firefox and Edge, but older Safari versions struggle with it, so check where the clip will be watched before you choose a browser for the job.
Very long videos need patience. A one-hour recording takes about one hour to re-record, so this tool fits short and medium clips best.
Frequently asked questions
Can I get the sound back from the muted copy? No. The muted copy has no audio track inside it. Use your original file if you need the sound again.
Does muting change the picture? The picture is recorded again at a fixed quality, so it is re-encoded, but the content is the same: same frames, same length, no crop and no filter.
Why is my muted file bigger than the original? Removing sound saves only a little space. File size is driven mostly by the picture, and the tool records the picture at one fixed quality level, which can outweigh a calmly compressed original.
Does my video leave my device? No. The file is read in your browser, recorded in your browser, and downloaded from your browser. Nothing is uploaded anywhere, and there is no account to sign into.
