ClearBoost — Volume Booster

Boost tab audio up to 600% — no ads, tracking, affiliate injection, or remote code.

Turn up quiet videos, calls, music, and streams to 600% while keeping control of distortion. Volume booster extensions should do one job. Too many in this category have abused user trust with adware, affiliate injection, tracking, or code delivered after installation. ClearBoost takes the opposite approach: a small, auditable extension with no content scripts and no access to the pages you read unless you explicitly enable optional per-site memory. TRUST BY DESIGN No ads, ever No affiliate injection No analytics or tracking No remote code No data collection Minimal permissions Open source FEATURES Smooth volume control from 0% to 600% One-click mute and reset Optional distortion prevention for high boost levels Live EQ presets: Flat, Bass Boost, Voice Clarity, and Treble Remember volume settings for individual sites Keyboard shortcuts for boost up, boost down, and mute Independent settings for every tab Automatic capture shutdown at normal 100% playback Light and dark themes ClearBoost Pro — $2.99 once, no subscription — includes the EQ presets and per-site volume memory. During launch, Pro features are free. Keyboard shortcuts are always free.
