What happens when you mute a video?
The exported file keeps the picture and leaves the sound out. The audio track is removed completely instead of being turned down to zero, so players have nothing to play. Because that data is gone, the file is also smaller than the original.
The picture is processed like any other export. You can still trim the clip, compress it, rotate it or change its format before you save. The original file on your computer is never changed, so you keep a version with sound.
How to remove the audio from a video
- Drop your video on the page, or choose it from your computer.
- Open the Audio tab and check that Remove the sound from the video is on.
- If you like, trim, rotate or compress the clip with the other tabs.
- Press Start, check the preview and download your silent video.

Why people remove the sound from a video
Common reasons are a noisy background, music you cannot publish, a private conversation caught by the microphone, or a clip that will play on a screen with the volume off. Silent clips also work well as website backgrounds, slide animations and short loops.
Muting is a quick way to make a file lighter too. Sound usually takes a smaller share of the size than the picture, but on a short clip the saving is still easy to notice. For a bigger reduction, use the Compress tab as well. You can add your own music later in an editor.
Which format and engine do you get?
Export as MP4, which uses H.264 video, or pick another format in the Convert tab. With the switch on, no audio track is written whatever the format. WebM exports use VP8 for the picture.
The work is done by FFmpeg.wasm, which is downloaded on your first export and cached afterwards. If FFmpeg cannot start, or the file is above about 1.6 GB, a native fallback built on Canvas and MediaRecorder takes over. It works in real time, so a 10 minute clip takes about 10 minutes.
Questions
Is it free to remove audio from a video?
Yes. There is nothing to pay and you do not need an account. This site adds no watermark. The video is processed in your browser and is never uploaded to a server.
Will the video file get smaller?
Yes. The exported video has no audio track, so that data is gone from the file. The saving depends on the clip, because the picture usually takes most of the size.
Can I get the sound back later?
Not from the muted file, since the audio track is removed. Your original video stays untouched on your computer, so open it again if you need the sound. You can also save it as MP3 or WAV first.
Does muting work with MOV, AVI or MKV files?
Yes. Other formats open the same way. If your browser cannot play the file, FFmpeg still converts it, but you get no live preview. Choose the output format in the Convert tab.
Does the picture quality change?
The export is a normal encode, so a very small quality change is possible. Keep your original until you have checked the result. MP4 output uses H.264 video, which most devices play.
