VolumeVault автор Pixelvault Labs

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.
