Volume Booster

Boost the volume of the current browser tab up to 600%, with mute and quick presets.

Volume Booster lets you turn the volume of any browser tab well past its normal 100% ceiling — useful for quiet videos, calls, or streams. Features: Boost volume up to 600% One-click mute Quick presets (50%, 100%, 200%, 400%) Per-tab volume that's remembered while the tab stays open Works alongside fullscreen video — the extension doesn't capture your tab's audio, so Chrome's fullscreen mode behaves exactly as it would without the extension How it works: Volume Booster attaches a small audio-boosting node directly to the video/audio elements on the page you're watching. It never records, stores, or sends your audio or browsing activity anywhere — all processing happens locally in your browser.
