About this extension

Too quiet? Turn it up to 500%.

VolumeVault boosts the volume of any tab with one click — perfect for too-quiet YouTube videos, soft dialogue, and weak laptop speakers.

Volume slider from 0% to 500%, adjustable live while audio plays
Remembers your level per site automatically
One click to return to normal

Private by design. Audio is processed on your device with the Web Audio API — it is never stored, uploaded, or sent anywhere. No accounts, no servers, no tracking. Zero host permissions at install.

Note: a few sites serve media in ways browsers won't let extensions process; VolumeVault tells you honestly when that's the case.
