Features

Everything Volume Master and Louder are missing

PRO

Up to 1000% Volume Boost

Push audio far beyond the browser's built-in limit. Quiet YouTube videos, muffled Netflix streams, and low Zoom calls become fully audible — even at max system volume.

PRO

5-Band Equalizer

Adjust bass, low-mid, mid, high-mid, and treble independently. Apply the Bass Boost preset for music, or the Voice Clarity preset for podcasts and calls.

PRO

Per-Site Memory

Set YouTube to Bass Boost and Zoom to Voice Clarity — the extension remembers your settings for each domain automatically. No re-adjusting when you switch tabs.

PRO

Keyboard Shortcuts

Bump volume up or down without touching the popup. Assign any key combination in Chrome's extension shortcuts settings.

FREE

Works on Any Tab

YouTube, Netflix, Twitch, Zoom, Google Meet, Spotify Web, local video files, news sites — if it plays audio in Chrome, the booster works on it.

FREE

100% Local, Zero Data Sent

The audio processing happens entirely inside your browser using the Web Audio API. No audio data is recorded, transmitted, or analyzed by any server.
