Sometimes the picture is what you want to share and the sound is the problem: a private conversation in the background, traffic and wind noise, copyrighted music playing in a shop, or a narration you plan to replace. Removing the audio track gives you a silent video that can be posted, embedded or edited without that baggage.
Drop one or several videos, press Convert, and each one comes back as a silent copy in its original format with -muted added to the file name. Because the video stream is copied rather than re-compressed, the result looks identical to the source and is usually ready far sooner than a full conversion would be, even for long recordings.
Removing a track is not the same as turning the volume down
A video file is a container holding separate streams: usually one video stream, one or more audio streams and sometimes subtitles. Muting a clip in a player or setting the volume to zero in an editor only hides the sound; the audio data is still inside the file and anyone who downloads it can play it. This tool writes a new file that contains no audio stream at all, so there is nothing left to un-mute.
Since only the audio is discarded, the remaining video stream can be copied byte for byte into the new container. No frames are decoded or encoded, which is why the operation is quick, why resolution, frame rate and sharpness are unchanged, and why the output file is smaller than the original by roughly the size of the soundtrack.
Good reasons to mute a video
Protecting privacy before sharing
Home videos, dashcam footage and screen recordings often capture voices, names or phone calls you did not mean to publish. A silent copy lets you share what was on screen without what was said nearby.
Background and hero videos for websites
Autoplaying video on the web must be muted to play in most browsers anyway. Shipping a file without an audio track saves bandwidth and removes any chance of sound starting unexpectedly for a visitor.
Preparing footage for a new soundtrack
When you plan to add music or a voice-over in an editor, starting from a silent clip avoids the original sound bleeding through and keeps the timeline tidy.
Avoiding copyright claims on background music
Platforms can flag or mute uploads because of a song playing in the background. Removing the sound before uploading sidesteps that, although it also removes everything else you might have wanted to keep.
How the tool removes the sound
The work is done by ffmpeg compiled to WebAssembly, running in your browser tab. That converter is about 31 MB and is fetched the first time you press Convert on any video or audio tool on this site; your browser then keeps it for later visits. For each file it runs the equivalent of telling ffmpeg to drop all audio and copy the video stream, and for MP4 and MOV it also moves the index to the front of the file so playback can start before a download finishes.
Files are handled one after another on a single thread. Each one can be up to 500 MB, and files above about 200 MB may need more memory than a phone or some browsers allow. When several videos are done, Download all (.zip) packs them into one archive.
Como usar esta ferramenta
- Drop one or more MP4, MOV, WebM, MKV or AVI files on the box above, or click it to browse.
- Check the list of queued files and remove any you added by mistake.
- Press Convert. The first time, the converter downloads before processing begins.
- Download each silent video, or press Download all (.zip) to save them together.
Limitations
- All audio tracks are removed. There is no option to keep one language track and drop another, or to lower the volume instead of deleting it.
- The output keeps the source container, so a MOV stays a MOV. Use Convert Video if you also need a different format.
- Because nothing is re-encoded, the file size only drops by the size of the audio; the video itself is not compressed further.
- Files over 500 MB are rejected, and very large files can run out of memory on mobile devices.
