Open the tab that plays sound and click the Volume Boost icon. 2. Drag the slider or tap 200%, 400% or 600%. Need exactly 250%? Click the number and type it. 3. Set it back to 100% later, and the volume booster extension lets go completely. ➤ A chrome volume booster that stays clean ▸ A built-in limiter stops loud peaks from clipping, so a boosted video sounds clear instead of crackling. ▸ Above 300% an orange warning reminds you that small speakers can be damaged at extreme levels. ▸ Turbo raises the ceiling to 1000% for really quiet recordings.

Clearer speech in podcasts, lectures and dialogue, without the underwater sound. 3️⃣ Night. Evens out loud and quiet parts, so whispers are audible and explosions don't wake the house. Open More for a 7-band equalizer from 60 Hz to 15 kHz with five presets. Your own presets follow you to other computers through Chrome sync, which makes it a handy equalizer for Chrome. 🔊 Volume mixer for everything that plays - Other tabs lists every tab that is playing sound, each with its own slider and mute button. - Turn down the music in one tab, boost a lecture in another and silence an autoplaying video in a third. - Click a name to jump to it, or mute the whole list at once. 💡 Volume control from the keyboard • Alt+Shift+Up turns the volume up by 10% and Alt+Shift+Down turns it down, without opening the popup. • Alt+Shift+M mutes or unmutes the current tab. • Alt+Shift+F mutes every other tab so you hear only this one, and pressing it again brings their sound back. Your level and sound settings are saved for every site. Turn on Auto for a site and they come back by themselves each time it loads, with a soft fade-in. Chrome asks for access to that one site only, and only when you turn Auto on. The toolbar badge always shows the current level. On video call sites, the popup shows a microphone button for the call. Click it to turn your mic off or on, even when the call is in the background. The volume booster presses the site's own mic button, so everyone sees your real state. It can't make your microphone louder, only mute it. Whatever plays, the chrome volume boost extension can make it louder. On ordinary players the sound is boosted right inside the page. For protected players on streaming services, Volume Boost switches to Chrome's tab capture by itself, and Chrome shows its sharing indicator until the level is back at 100%. 🔒 Private and light No network requests: the audio booster works offline and doesn't read or change your data on all websites. The mixer needs tab titles, which is why Chrome mentions your browsing history, and nothing is stored or sent. The debugger permission is used for a single real click on a call site's mic button, and tab capture is only the fallback for protected players. The sound goes straight to your speakers and is never recorded. ❓ Quick answers How do I make Chrome louder than 100%?
