See It in Action

The Problem We Solve

Your browser caps volume at 100%. This extension removes that limit. Volume Booster lets you increase any tab's audio up to 600%. Open the popup, move the slider, done.

What Volume Booster Does

Built with precision to solve real problems without adding complexity.

Boost 0% to 600%

Per-Tab Control

Live Badge

Dynamics Compression

Built-in compressor tames boosted peaks to prevent distortion and clipping.

Dynamic Media Detection

Automatically detects and boosts new audio and video elements as they appear on the page.

Zero Network

No network requests, no analytics, no remote code. Everything stays local.
