About this extension
Volume Booster lets you increase the volume of a browser tab beyond the default 100%, up to 500%, or lower it all the way down to 0%. Whether you’re watching quiet videos, listening to music, or streaming audio, this extension gives you easy control over your sound levels.
Features include:
Some sites don’t allow extensions to change their audio (Bandcamp, for example), and a few players can’t be reached yet. When that happens, Volume Booster tells you instead of silencing your audio.
This extension does NOT:
Everything runs locally on your device. No personal data is collected, transmitted, or shared. The only things saved are your theme and whether interface sounds are on, and they stay on your device in the browser’s local storage.
Warning: Increasing volume beyond 100% can cause distortion or damage speakers/headphones. Use responsibly and adjust gradually.
Features include:
- Amplify tab audio up to 5x louder, or lower it below 100%
- Simple, minimalist popup for quick adjustments, with light and dark themes
- A status line that tells you what's possible on the current page
- No accounts or tracking — just pure volume control, with no special permissions needed
- Lightweight and unobtrusive, with a clean design
