Set any tab’s volume to 600%
Chrome stops at 100%.
Loudness doesn’t. Every tab gets its own volume, from silent to six times louder, without the crackle. Press play, then drag the fader.
Best with headphones. Drag the fader, or use the arrow keys.
When 100% isn’t loud enough
Some tabs are quiet even with every volume control at the top. Pick one to hear how much room Loudness adds.
Loud shouldn’t mean broken.
Most boosters multiply the sound until it crackles. Loudness has a limiter that catches the peaks first, so 600% still sounds like music. Switch it off to hear the difference.
Both play at 600%, so turn your computer’s volume down a little first.
Control every tab from one place
Click Loudness in the toolbar and the tab you’re on gets its own fader. This one works: it controls the music on this page.
- Every tab keeps its own level. Boost a lecture, turn a playlist down, and both stay put while you switch.
- Bass, Voice and Mono. Warmth for music, clearer words for talks and calls, and both channels in one earbud.
- See everything that’s playing. Jump to a noisy tab or change its level from the list.
- The icon shows the level. A small badge such as 250 marks every tab that isn’t at 100%.

Change the volume from your keyboard
The shortcuts work on the tab you’re watching, even in fullscreen. They work on this page too, so try them now.
Each press moves 10%. You can change the step, or the keys, in Loudness’s settings.
It only hears what you ask it to
Loudness asks for no website access. It changes a tab’s sound only after you click its icon or press its shortcut on that tab.
- Website access
- None. Loudness can’t read or change the pages you visit.
- Data sent anywhere
- None. No analytics, accounts or ads.
- Network
- None. Sound is processed on your computer and never leaves it.
- Permissions
- Tab audio, the list of open tabs, and storage for your settings.
- Blue tab icon
- Chrome shows it while a tab’s sound runs through Loudness. It’s a reminder, not a recording.
Read the privacy policy. It’s short.
In your language
Loudness comes in all 54 languages Chrome supports, and uses yours automatically.

Questions
Anything else? Support has quick fixes, and a person reads every email.
Is it really free?
Yes. No ads, no account, no premium tier. Loudness is made by Mutables, a small studio, and it stays free.
Why does a tab show a blue icon while I adjust it?
That’s Chrome telling you the tab’s sound runs through an extension. Loudness only changes the volume. Nothing is recorded or sent anywhere.
Will very high levels damage my speakers?
The built-in limiter catches the peaks that cause crackling, so boosted sound stays clean. Still, go easy at the top of the scale: small speakers and your ears both have limits.
What happens to fullscreen video?
While a tab is adjusted, Chrome may keep fullscreen video inside the window. Press F11 (⌃⌘F on a Mac) to fill the screen, or set the tab back to 100% and Loudness hands the sound back to Chrome a moment later.
Does it work on every site?
On any site that plays sound in a tab: YouTube, Netflix, Spotify, Google Meet, Zoom, podcasts, lectures. Chrome doesn’t allow extensions on its own pages (chrome://) or on the Chrome Web Store.
Can it remember a level for a site?
Yes, if you turn on per-site memory in its settings. Levels are stored on your computer only and never synced.
Why does it need the “tabs” permission?
To list the tabs that are playing sound, so you can switch to one or adjust it from the popup. Loudness can’t read or change the pages themselves.
Common volume problems, answered
- Why is YouTube so quiet, even at full volume? YouTube evens out loudness by turning loud videos down, but it never turns quiet ones up, so a video uploaded quiet stays quiet.
- How do I make a Google Meet or Zoom call louder? If the call is still too quiet with your computer at full volume, boost the call’s tab.
- How do I change the volume of just one tab in Chrome? Chrome itself can only mute a site: right-click the tab and choose Mute site.
- Can Chrome’s volume go above 100%? Not on its own: 100% in Chrome means a page’s sound at its original level, and there’s no setting above it.
- Why is Netflix so quiet, and how do I hear the dialogue? Films and series are mixed with a wide range between quiet dialogue and loud action, which laptop speakers struggle to reproduce.
Turn it up.
Free for Chrome. Add it, click its icon on any tab, and slide.
