Volume Booster

Up to 600% volume boost

Volume Booster gives you full control over the sound in your browser. Turn any tab up to 600% of its normal volume, shape the audio with a built-in equalizer, and jump between every tab that's playing sound — all from one simple popup. Whether a video is recorded too quietly, a meeting is hard to hear, or a song needs more punch, Volume Booster lets you push past your computer's normal limit and hear everything clearly. ━━━━━━━━━━━━━━━━━━━━ KEY FEATURES ━━━━━━━━━━━━━━━━━━━━ • Boost volume up to 600% — go well beyond the standard 100% maximum on any tab. • Per-tab control — each tab keeps its own volume level independently. • Built-in equalizer — quick presets for Voice boost and Bass boost, plus manual control over frequency, Q, and gain. • See every audio tab — instantly view all tabs currently playing sound and switch to any of them with one click. • Remembers your levels — restore the volume you last used for a website. • Keyboard shortcuts — press 0–6 to set volume from 0% to 600%, use the arrow keys for fine adjustments, and set your own shortcut to open the popup. • Mouse-wheel adjustment — scroll over the slider to change the volume (direction can be inverted in settings). • Dark mode — a comfortable look for low-light browsing. • Lightweight and fast — a clean popup with no account or sign-up required. ━━━━━━━━━━━━━━━━━━━━ HOW TO USE ━━━━━━━━━━━━━━━━━━━━ 1. Play audio or video in any tab. 2. Click the Volume Booster icon in your toolbar. 3. Drag the slider (or use the number/arrow keys) to set the volume. 4. Open Settings to enable dark mode or change the scroll direction. ━━━━━━━━━━━━━━━━━━━━ ABOUT ADS ━━━━━━━━━━━━━━━━━━━━ Volume Booster is free and supported by advertising. The extension shows a single small, clearly labeled ad banner inside its popup window. The banner is marked "Ad", and you'll always see a confirmation prompt before any ad link opens — nothing opens automatically. Ads are never injected into the web pages you visit. This advertising helps keep the extension free to use. ━━━━━━━━━━━━━━━━━━━━ PERMISSIONS — WHY THEY'RE NEEDED ━━━━━━━━━━━━━━━━━━━━ • Tab capture / audio access — required to read and amplify the sound of the current tab. • Tabs & active tab — to detect which tabs are playing audio and let you switch to them. • Storage — to save your volume preferences and settings on your own device. • Site access — used only to display the ad banner and to confirm an ad link before it opens. The extension does not read, collect, or modify the content of the pages you browse. ━━━━━━━━━━━━━━━━━━━━ PRIVACY ━━━━━━━━━━━━━━━━━━━━ Your volume settings are stored locally on your device. Volume Booster does not collect your browsing history or personal data. The in-popup ad banner is loaded from a remote ad service to display current ads. Enjoy clearer, louder, better-controlled sound on every tab. Install Volume Booster and take charge of your browser's audio.
