Overview

Boost or lower the volume of YouTube (or any tab), from 0% to 500%.

Some videos and streams are just too quiet, even at 100% system volume. YouTube Volume Booster lets you boost any tab's audio up to 5x, or turn it down below normal, right from the toolbar. Features: - Volume range from 0% to 500% per tab - One-click mute, remembers your last volume - Scroll to adjust volume without opening the popup - Volume automatically re-applies after page navigation - Light and dark mode - No account, no tracking, no data collection — everything runs locally
