Volume Booster allows you to control volume and amplify sound in the browser up to 600%.
Read the publisher’s full description
The simplest and most reliable way to increase volume in your browser. Volume Up Plus is a powerful and easy-to-use extension that allows you to increase sound volume up to 600% on any tab. Enhance the audio quality of music and videos on YT, Vimeo, Dailymotion, and other platforms. Key Features: ✔ Boost volume up to 600% – customize the sound to your preference ✔ Tab-specific volume control – adjust sound separately for each tab ✔ Fine-tuned adjustment – volume range from 0% to 600% ✔ Bass Booster – rich low frequencies for deep sound ✔ Quick access – switch to any audio-playing tab with one click ✔ Simple and convenient – minimalist design and intuitive interface Shortcuts: When the popup is open (only when it is active), the following hotkeys are available for volume control: <code>• Left Arrow / Down Arrow – decrease volume by 10% • Right Arrow / Up Arrow – increase volume by 10% • Space – instantly boost volume by 100% • M – mute/unmute </code> These keyboard shortcuts provide quick and convenient volume adjustments directly from the popup, ensuring maximum control with just a single keystroke. Full-Screen Mode: Browser does not allow full-screen mode when using extensions that modify sound. That’s why you will always see a blue indicator on the tab bar, signaling that audio is being processed. This is a built-in security measure. Tip: To hide the browser interface, press F11 (Windows) or Ctrl + Cmd + F (Mac). Permissions Explained: “Read and change all your data on the websites you visit” – required to connect to AudioContext, manage sound, and display a list of audio-playing tabs. Completely free and ad-free! Install Volume Up Plus and enjoy powerful sound without limits! Privacy Assurance: Your privacy is our priority. We do not collect, store, or share personal data. Volume Up Plus operates entirely on your device, ensuring complete security and confidentiality. Our extension strictly follows extension store privacy policies to guarantee a safe and secure browsing experience.
