Mute video

Drop the sound and keep the picture. The page tries to copy the video stream. If the container will not allow that, it re-encodes the picture and still omits the audio.

Choose a file or drop it hereA clip whose sound you want gone.

The picture is copied when the container allows it, and re-encoded when it does not. The audio track is not in the download. The source file stays as it was.

How to use it

Choose a clip. The job asks ffmpeg to copy the video and map no audio. When the source codec cannot be copied into MP4, the page re-encodes with libx264 ultrafast and still writes no audio track.

A silent file is what you want for a social post that will use a platform music bed, or for a screen recording whose microphone you do not want.

The source file is unchanged. If the copy path works, the picture is the same encode. If the fallback runs, it is a new encode and can look slightly softer.

Tips

Check the preview with the sound on in the page. A successful mute is quiet.
If you also need a shorter clip, trim first so the re-encode, when it happens, is shorter.
This does not beep, bleep, or duck. It removes the track.

FAQ

Is the audio recoverable from the download?

No. The new file has no audio track. Keep the original if you might want the sound later.

Why would it re-encode?

Some codecs and odd pixel formats cannot be copied into a plain MP4. The fallback still produces a silent file.

Does mute upload the video?

No.

License

Encoding uses the single-thread ffmpeg.wasm build shipped with Cutshed. The JavaScript wrapper (@ffmpeg/ffmpeg and @ffmpeg/util) is MIT. The core binary is GPL-2.0-or-later because the build enables GPL components, including libx264, libmp3lame, libvorbis, and native AAC and FLAC. That license covers the encoder, not your recording.
