Volume Booster — Boost Sound Up to 800%

Boost any tab's volume up to 800% with sound presets and a 10-band equalizer. Crystal-clear, distortion-free, fast, and private.

Volume Booster is a simple, powerful volume booster and sound equalizer for your browser. Turn up the volume on any tab — up to 800% louder than the browser's normal maximum — so quiet videos, music, podcasts, games, and online meetings are finally easy to hear. Some tabs are just too quiet, even at 100%. Volume Booster fixes that instantly, and a built-in smart audio engine keeps everything clean: an automatic compressor and limiter prevent clipping and distortion, so louder still sounds crisp and clear. BOOST VOLUME UP TO 800% Increase the volume of the current tab with a smooth, responsive slider, or jump straight to 2×, 4×, 6× or 8×. Make quiet audio loud without the harsh distortion you get from turning your speakers all the way up. 10-BAND GRAPHIC EQUALIZER Shape your sound across 10 bands (31 Hz to 16 kHz). Add deep bass, brighten the highs, or make voices clearer. The equalizer stays tucked away until you need it. SOUND PRESETS FOR EVERY MOMENT One tap for the right sound: Bass Boost, Treble Boost, Voice Boost, Movie, Gaming, Music, Podcast, and Night Mode — plus Default. You can also save your own custom presets. REMEMBERS EVERY TAB Each tab keeps its own volume, preset, and mute state, and your settings are restored automatically when you come back to a site. MORE TOUCHES • One-click mute and reset • Keyboard shortcuts for volume up, volume down, mute, and reset • Clean, lightweight popup with light and dark themes • No ads and no clutter CRYSTAL-CLEAR, DISTORTION-FREE SOUND Your audio is processed in real time through a gain stage, a 10-band equalizer, a dynamics compressor, and a limiter that keeps peaks under control. The result: much louder sound that still stays clean. PRIVATE BY DESIGN Everything runs locally, on your device. Volume Booster does not collect, track, sell, or share any data. No accounts, no analytics, no browsing history — ever. It cannot read the content of the pages you visit. PERMISSIONS • Tab capture — to capture a tab's audio so it can be boosted and equalized • Storage — to remember your volume, presets, and settings on your device • Tabs / active tab — to identify the tab you're on so the boost applies to it Volume Booster requests no host permissions. Requires Google Chrome 116 or newer. Install Volume Booster and enjoy every video, song, call, and game the way it was meant to be heard.
