Mute Video

How Mute Video works

Muting removes the audio track entirely and copies the video stream into a new file unchanged. Because the picture is not re-encoded, even a long video is done in seconds and looks exactly like the original.

That is different from turning the volume down in an editor: the result has no sound track at all, which is what platforms and presentations mean by a silent video, and it is slightly smaller because the audio data is gone.

The work is done by ffmpeg running as WebAssembly in this tab. The engine downloads the first time, about 32 MB, and your browser keeps it; the video itself is never uploaded.

The muted file is named after the original with -muted added, so nothing is overwritten. It works with MP4, MOV, MKV, WebM, AVI and most other formats, and the result keeps the original container, so a MOV from an iPhone stays a MOV that plays in the same apps as before. If you want to keep the sound in a separate file, use the matching converter first, such as MP4 to MP3, and then mute the video here. Muting on your own device also means private clips, such as recordings of children, meetings or home videos, never reach a server. A muted clip is also a common requirement for autoplaying video on websites, since browsers only autoplay videos without sound, and a silent file is smaller and loads sooner.

Mute Video options explained

When to use it

People mute videos to remove background chatter or wind noise before sharing, to strip copyrighted music that would get a clip blocked, to prepare background loops for websites and presentations, or to add a new soundtrack in an editor later.

If you want to replace the sound rather than remove it, mute the video here first, then add the new track in any editor; starting from a silent file avoids two soundtracks playing at once.

About these video tools

The video tools use ffmpeg, the program behind most video software, compiled to WebAssembly so it runs in your browser. The engine is downloaded once, about 32 MB, and cached, so later visits start straight away. Some operations only copy streams, which is fast and lossless; others must re-encode every frame, which is slower because it runs on your own processor rather than a server farm. Each tool says which it does. Keep the tab in front while it works, because browsers slow down background tabs. For very long 4K recordings, a desktop editor will be quicker, but for the everyday clips people trim, mute and rotate, the browser is enough and the video stays private.

Mute Video troubleshooting

The video will not load

Some rare codecs cannot be copied into their own container. Convert the video to MP4 first, then mute the MP4.

The first run is slow

The converter engine, about 32 MB, downloads the first time. After that it is cached and muting takes seconds.

A phone runs out of memory

Very long videos may be too big for a phone browser. Use a computer, or trim the video into parts first.

How to use Mute Video, step by step

1. Press "Choose a video" or drag files onto the box.
2. Set the options if you need to; the defaults suit most uses.
3. Press "Remove audio". The work happens on your device.
4. Save the result with its download button.

Is it safe to do this online?

With most online tools, "online" means your file is uploaded to a company's server, processed there and kept for a while before it is deleted. Here it is not. The page downloads the tool's code to your browser, and your file is read and processed inside the tab on your own device. It is never sent to TapToConvert or anyone else.

You can check this yourself: once the page and its engine have loaded, turn off Wi-Fi and the tool still works. That also means there is no queue, no daily limit and no file size cap set by a server; the only limit is the memory your browser gives a single tab.
