Volume Booster - Tab Volume Control & Equalizer

Boost any tab's volume up to 600%, with a bass and voice equalizer and a limiter that stops crackling. No ads, no tracking.

Boost any tab's volume up to 600%. Quiet video? Soft-spoken podcast? Laptop speakers that just aren't loud enough, even at full volume? Volume Booster makes any tab louder with one slider, and keeps it sounding clean. ★ BOOST UP TO 600% Drag the slider or tap a preset: Mute, 100%, 200%, 300% or Max. Scroll the mouse wheel over the slider for fine control. The badge on the icon shows each tab's volume at a glance. ★ LOUD WITHOUT THE CRACKLE Most boosters distort badly at high volume. Volume Booster has a built-in limiter that catches the peaks, so even 400% stays clear. You can switch it off any time. ★ EQUALIZER WITH PRESETS • Bass boost – fuller music and movies • Voice – clearer dialogue, podcasts, lectures and calls • Treble – crisper detail • Or set bass, mid and treble yourself ★ EVERY TAB GETS ITS OWN VOLUME Boost a video in one tab and leave your music in another alone. See all your boosted tabs in one list and change or stop any of them. ★ MUTE OTHER TABS IN ONE CLICK Something autoplaying somewhere? Mute every other tab that's making sound, and unmute them again just as fast. ★ REMEMBERS EACH SITE Set a site to 250% once, and it's back at 250% the next time you open Volume Booster there. ★ FULLSCREEN STILL WORKS Boosting a tab's audio normally traps fullscreen video inside the browser window. Volume Booster fixes that, so fullscreen works like normal. ★ PRIVATE AND AD-FREE • No ads, no account, no tracking • No "read and change all your data on websites" permission • Your settings never leave your browser HOW TO USE 1. Open a tab that's playing sound. 2. Click the Volume Booster icon. 3. Drag the slider. That's it. Click Reset to go back to normal. Works on any website that plays sound: videos, music, podcasts, live streams, online courses and video calls. Note: Chrome doesn't allow extensions on its own pages (chrome://) or the Chrome Web Store, and only one extension can capture a tab's audio at a time, so turn off any other volume extension on that tab.
