Video Volume Booster

About
Increase the volume of a video online, free. Make a quiet video louder up to 500%, turn a loud one down, or normalize it to as loud as it can go without distortion. It runs in your browser, so the video is not uploaded.
When you boost past 100%, the loudest moments are rounded off smoothly instead of being clipped, so speech doesn't crackle. Normalize finds the loudest moment in the video and brings the whole sound up until that moment sits just under full level, without changing the balance between quiet and loud parts.
Only the sound is written again: the picture is copied untouched, so it keeps its full quality. A browser can't play a file louder than 100%, so the preview tops out there; download the result to hear the boost. For hiss or hum, clean the sound first with the noise remover.

Up to 500%. Very large boosts make background noise louder too.
