About this extension
The ultimate tool to amplify sound and enhance your listening experience.

Volume Booster is a powerful and easy-to-use extension that allows you to boost volume up to 600% on any tab. Improve the audio quality of music, videos, and any online content on YouTube, Vimeo, Dailymotion, and other platforms.

Key Features:

✔ Amplify volume up to 600% – adjust sound levels for an enhanced experience
✔ Per-tab volume control – set individual volume levels for different tabs
✔ Fine-tuned adjustments – precise volume range from 0% to 600%
✔ Bass Booster – rich, deep bass for immersive sound quality
✔ Quick access – easily switch between tabs playing audio
✔ User-friendly interface – simple, intuitive, and lightweight

Shortcuts:

When the popup is open and active, you can use the following hotkeys to control volume:
• Left Arrow / Down Arrow – lower the volume by 10%
• Right Arrow / Up Arrow – raise the volume by 10%
• Space – instantly increase the volume by 100%
• M – toggle mute/unmute

These shortcuts offer a fast and efficient way to adjust volume directly from the popup, giving you seamless control with a single keystroke.

Full-Screen Mode:

Browser does not allow full-screen mode when using extensions that modify sound. A blue indicator will always appear on the tab bar to signal that audio is being processed. This is a built-in security measure.

Tip: To maximize your viewing experience, press F11 (Windows) or Ctrl + Cmd + F (Mac).

Permissions Explained: “Read and change all your data on the websites you visit” – required to modify audio settings via AudioContext and display a list of audio-playing tabs. Install Volume Booster today and enjoy powerful, crystal-clear sound without limits!

Privacy Assurance:

Your privacy is important to us. We do not collect, store, or share personal data. Volume Booster operates entirely on your device, ensuring complete privacy and security. Our extension fully complies with extension store privacy policies, guaranteeing a safe and secure browsing experience.
