How the level works
100% is the original volume. Lower values make the whole audio track quieter, and 0% removes the audio track entirely. The change applies evenly across the video; it does not target a single voice or sound.
Lower video volume
Set the sound anywhere from 0 to 200%, then hear the result.

How it works
Choose a video
Open an MP4, MOV or WebM file that has sound.
Set the level
Pick a level below 100% to make it quieter, or above to boost it.
Listen and download
Export, play the result to check the level, and save it.
Good to know
Boosting has a limit
Values above 100% raise the volume, up to 200%. If the original is already loud, boosting can clip, which makes the peaks distort. Listen to the exported file before sharing, and pick a lower level if it sounds harsh.
Formats and limits
The volume tool works with MP4, MOV and WebM. You can process up to 10 files with a combined size of 500 MB on desktop or 150 MB on mobile, all in your browser with an FFmpeg engine.
Questions and answers
Does 0% mute the video?
Yes. At 0% the audio track is removed, the same result as muting.
Can boosting damage the sound?
It can cause clipping when the audio is already loud. Check the result and lower the level if you hear distortion.
Can I lower background noise but keep speech?
No. The level changes the whole audio track; noise removal and voice isolation are not available.
Is the video uploaded?
No. It is processed on your device, in the browser.
