VolumeBooster — a little louder

Smooth, independent volume control for your tabs. Local audio processing, up to 400% boost, and fullscreen shortcuts.

Bring quiet videos and music to a comfortable level with VolumeBooster. • Adjust the current tab from 0% to 400% with presets, a slider, +/− and Reset. • Mute without losing your chosen level. • Use optional look-ahead peak protection and a live output meter. • Optionally remember a site’s volume and protection setting locally. Access is requested only for the host you choose to remember. Forget removes that preference. • See clear player compatibility and paused-output guidance, with Retry audio. • Customize keyboard shortcuts in Chrome’s own settings. Compatible HTML audio/video players retain native fullscreen. Other sources may use tab audio capture, where Chrome can limit native fullscreen; the popup identifies this mode. Automatic restoration processes compatible players and never starts tab capture. All processing runs on your device. No microphone access, recordings, uploads, accounts, ads or tracking. Saved preferences contain only the exact site origin, volume and protection setting. Private-window preferences are not saved. Free and open source under the MIT license. Protected media, cross-origin players and other audio extensions can limit compatibility. This extension cannot unmute your device or a muted website player. Increase gradually and lower the level if sound becomes rough.
