Volume Booster 600

Boost any tab's volume up to 600% with an adjustable bass boost and an anti-distortion limiter.

Too quiet? Volume Booster 600 turns any Chrome tab up to 600% — videos, music, podcasts, lectures and calls. ★ VOLUME UP TO 600% Drag the slider or tap a preset (100%, 200%, 300%, 400%, 600%). The mouse wheel over the popup adjusts in 10% steps. ★ BASS BOOST Add up to +20 dB of low end with one slider, or pick Off / Low / Medium / High / Max. ★ ANTI-DISTORTION LIMITER A built-in limiter keeps the sound clean at high boost instead of crackling. Turn it off if you want raw output. ★ PER-TAB CONTROL Every tab keeps its own level. The toolbar badge shows each tab's boost, and "Stop all" resets everything in one click. Your last settings are remembered for new tabs. ★ PRIVATE BY DESIGN All audio is processed locally in your browser. No accounts, no tracking, no data collected, nothing sent anywhere. HOW TO USE 1. Open a tab that's playing sound. 2. Click the Volume Booster 600 icon. 3. Move the Volume or Bass slider — boosting starts right away. 4. Close the popup; the boost keeps running. Click the power button to turn it off. GOOD TO KNOW • Chrome shows a small "sharing" indicator on boosted tabs. That's how Chrome lets extensions process tab audio — nothing leaves your computer. • Chrome doesn't allow extensions on chrome:// pages or the Chrome Web Store. • Very high volume can damage hearing and speakers. Start low. Free forever. If it helps you, you can support development with the "Buy me a coffee" button in the popup.
