Video Volume Changer
Make a video louder (up to 300%) or quieter, or even out its loudness, and save it without changing the picture.
Settings
Press play on the video above to hear the new volume. The picture is copied as it is, so this is quick and keeps full quality. Above 100%, a limiter stops loud parts from crackling.

FAQ
Is my video uploaded anywhere?
No. The video is processed by your own browser, on your phone or computer, with a free video engine (ffmpeg). It never reaches our server, so private and family videos stay private.
How much louder can I make a video?
Up to 300%. Above 100%, a limiter keeps loud parts from crackling, so quiet recordings become clearly louder without harsh distortion.
What does “Normalise loudness” do?
It measures the sound and evens it out to the loudness used by YouTube and streaming apps (-16 LUFS). It's the easiest fix for a video that's too quiet, or has very loud and very quiet parts. The volume slider is applied after that.
Does it change the picture?
No. The picture is copied exactly as it is, so the video quality stays the same and it only takes a few seconds.
How do I remove the sound completely?
Use the Remove Audio from Video tool, which deletes the sound track instead of making it silent.
