How to control volume for a browser tab vs the whole browser on Mac

A single tab and the whole browser are two different layers of audio, and you control them with two different tools. For one tab, use the browser's own controls — right-click the tab and choose Mute Tab, or add an extension for graded volume. For the whole browser against everything else on your Mac, you need a per-app mixer, because macOS sees Chrome or Safari as a single app and gives it one volume.

People type this search after one of two very different frustrations. Either a YouTube tab is blasting while a docs tab should be quiet — that's a within the browser problem — or the browser as a whole is drowning out Spotify or a Zoom call — that's a browser versus other apps problem. They feel similar, but the fix for one does nothing for the other. Sort out which one you have first and the rest is easy.

Why a tab and the browser are different things to your Mac

macOS routes audio per application. Chrome is one app; Safari is one app. A tab is not a separate process the system can see, so as far as macOS is concerned every tab in a browser is the same single stream of sound. That's the key fact behind everything below: the operating system can only ever turn the whole browser up or down. Anything finer than that has to happen inside the browser itself, where tabs actually exist.

So the right tool depends entirely on the layer you're aiming at. Want one tab quieter than another tab? Stay inside the browser. Want the browser quieter than your music app? Step out to a per-app mixer. Mixing up the layers is why people install a volume app, point it at Chrome, and wonder why it won't single out the one loud tab.

Controlling one tab: stay inside the browser

Every major browser on the Mac can silence a single tab on its own, for free. When a tab is playing audio, a small speaker icon appears on it. Right-click the tab and choose Mute Tab, or click the speaker icon directly. Chrome, Safari, Firefox, and Edge all support this. Other tabs keep playing — only the one you picked goes silent.

Mute is the part every browser does well. Graded volume — a tab at 40% rather than just on or off — is where they differ. Chrome and Safari give you mute, not a per-tab volume slider, so for true tab-level volume you add a browser extension built for it (Volume Master and similar tools do this for Chromium-based browsers). That extension lives inside the browser and only knows about tabs, which is exactly why it can do what a system audio app can't.

The honest limit: a browser extension can only touch what plays through that browser. It can't reach Spotify, a video call, a game, or system alerts. The moment your problem involves audio outside the browser, a tab tool runs out of road.

Controlling the whole browser: step out to a per-app mixer

When the browser itself is the loud one — YouTube versus your Zoom call, a web player versus Spotify — you're balancing the browser against other apps, and macOS has no built-in mixer for that. The system volume keys move everything at once. To give the browser its own level you install a per-app volume app, which sits at the OS audio layer and hands every running app a separate fader.

These tools all control the whole browser as one channel — that's the point, and also the boundary. They cannot pick a tab out of the browser, because, again, a tab isn't an app. What they do is let you pin the browser at, say, 30% while Spotify stays at 80% and your call stays at 100%, and keep it that way without babysitting it. If your real need is the broader version of this — one app down while everything else stays put — the walkthrough in lower one app's volume without lowering everything covers it end to end.

Which per-app mixer for the browser channel

If the browser-against-everything problem is yours, a few apps solve it and they're honestly different. Background Music is free and open source, lists running apps in the menu bar, and is a fine no-cost start. SoundSource from Rogue Amoeba is the deep option — per-app volume, routing, and EQ in one menu-bar panel — at a one-time price around $47. Fader is the keyboard-first take at $19.99 one-time, built around reaching the control fast.

They all set a browser level. The difference you feel day to day is how you get to it. A menu-bar list means moving to the menu bar, clicking the icon, finding the browser's row, and dragging — fine once, a tax when the browser jumps in volume every time you open a new video. Fader's bet is that the fastest controller you own is the keyboard already under your hands: hit a toggle hotkey and letter keys become faders, so dropping the browser is a keystroke from inside whatever you're doing. For the same logic applied to a hotkey that mutes one app outright, see how to set a keyboard shortcut to mute an app on Mac.

A quick decision guide

Use this to skip straight to the fix. If the loud thing is one website while another website should stay quiet, and both are in the same browser, that's a tab job — mute the tab or add a volume extension. If the loud thing is the browser compared to a non-browser app, that's a mixer job — give the browser its own fader. If you sometimes need both, that's normal: a tab tool and a per-app mixer don't conflict, because they work at different layers.

Bottom line

One tab and the whole browser live on two different layers, and trying to fix one with the other tool is the usual dead end. For a single tab, the browser already has you covered — Mute Tab is free, and an extension adds graded volume. For the browser against the rest of your Mac, macOS gives you nothing built in, so a per-app mixer is the real fix. If you ride that browser channel all day and want it a keystroke away, that's exactly what Fader is built for.
