Video Volume Studio
Give quiet clips a lift or bring loud recordings down a little. Listen as you adjust, from silence to three times the volume, then save a new video.
01
Processed on your device
Reading, audio adjustment and export happen inside your browser. The engine loads from this site; your video is never uploaded.
02
Keep the picture intact
Compatible H.264 video is copied. Other formats convert to H.264; audio is saved as AAC. Conversion may affect quality, and odd dimensions are padded to even values.
03
Short clips are easier
Use a recent Chrome or Edge. The limit is 250 MB; devices with limited memory may need smaller files. Videos without audio cannot be adjusted.
