Is my video uploaded?

No. Everything runs in your browser tab, and removing the sound from an MP4 or MOV does not even load the FFmpeg engine.

Mute Video Online — Remove Sound, Change Volume or Bleep Parts, Free & Private

Q: Is there a file size limit?

Not for MP4 and MOV: the file is rebuilt around the untouched video data, so multi-gigabyte phone videos work. WebM, MKV and other formats go through FFmpeg in browser memory, which limits them to about 900 MB on a computer and less on phones.

Remove the sound from a video, make it louder or quieter, even out the loudness, or silence or bleep just a few seconds. The picture is never re-encoded, so the quality stays exactly the same.

How to mute a video

Drop a video onto the box above.
Choose Remove sound, Volume, Even out or Mute parts. The player previews volume changes and muted parts.
Click the button and save the new video.

The picture is never touched

Most online tools decode and re-compress the whole video just to change its sound, which takes long, softens the picture and often drops the recording date. Here the video data is copied byte for byte. For MP4 and MOV files the tool rebuilds the file around the original picture data in your browser and only swaps the sound track, so it works on multi-gigabyte phone videos, keeps the date, location and timecode, and is done in seconds.

Removing sound for privacy

When you remove the sound, the original sound data is not left hidden in the file: the new file is built from the picture only. The same goes for muted or bleeped parts: the sound track is encoded again from scratch with those seconds replaced, so the original speech cannot be recovered from the file.

Evening out loudness

Even out measures the whole sound track the way broadcasters and streaming sites do (EBU R128 / ITU-R BS.1770), then applies a single gain so the video lands on the target: -14 LUFS for YouTube, Instagram and TikTok, -16 LUFS for podcasts, -23 LUFS for TV. Because it is one even step, quiet and loud moments keep their balance instead of being squashed.

Frequently asked questions

Is the sound really gone, or just silenced?

Really gone. The new file is built from the video data only, so the original sound is not hidden inside it.

Does muting lower the video quality?

No. The picture is copied byte for byte and never re-encoded. Only the sound track is removed or replaced.

Is there a file size limit?

Not for MP4 and MOV. WebM, MKV and other formats go through FFmpeg in browser memory, which limits them to about 900 MB on a computer and less on phones.
