How to lower Netflix's volume in your browser on Mac

Netflix has no Mac app — it plays in a browser tab — so the quickest way to lower its volume is the slider inside Netflix's own player, which quiets Netflix without touching your other apps. What that slider can't do is balance Netflix against a call or your music: the browser sends all of its audio through one master output, and macOS has no per-app volume mixer. To hold Netflix at a fixed level below everything else, you need a per-app mixer — and the fastest of those live on your keyboard.

This trips people up because Netflix feels like an app but behaves like a web page. There's no icon in your Dock with its own audio channel, no per-app slider in System Settings. When a trailer blasts in or a show mixes dialogue too quiet and the score too loud, most people reach for the Mac's volume keys — and watch everything else drop with it. Here's every real way to lower Netflix specifically, where each one stops working, and the fastest fix.

First: Netflix has no Mac app, and that changes everything

Netflix doesn't ship a native macOS application. You watch it in Safari, Chrome, Arc, or Firefox — full stop. That single fact explains the whole problem. To macOS, "Netflix" isn't a separate audio source; it's audio coming out of your browser. Any tool that works at the app level sees Chrome or Safari, not Netflix. So the two built-in controls you actually get are Netflix's in-player slider and your browser's per-tab mute — nothing finer, and nothing that survives closing the tab.

Option 1 — Use Netflix's own volume slider (free, but only Netflix)

Move your pointer over the video and the player controls appear. On the left is a speaker icon with a volume slider; drag it down and Netflix gets quieter on its own, without moving your system volume. This is the right first move — it's free, it's instant, and it affects Netflix and nothing else.

Where it stops: the slider only rides Netflix down against silence, not against your other apps. If you're on a call in another window, or have Spotify running, Netflix's slider can't hold it at, say, 40% while the call stays at 100%. And the setting isn't sticky in a useful way — it lives with that player session, so a new tab or a fresh episode can start you over. For "just make this quieter right now," it's perfect. For a mix you keep, it isn't built for that.

Option 2 — Mute the Netflix tab in your browser (free, but all-or-nothing)

Every major browser can mute a single tab. In Chrome and Arc, right-click the Netflix tab and choose Mute site (or click the little speaker icon on the tab). In Safari, click the speaker icon that appears in the address bar or on the tab. It's the fastest way to kill Netflix's sound entirely while a call comes in.

But mute is binary — full volume or silence, no in-between. It's a switch, not a fader. And in most browsers it mutes the whole site or tab, so it's coarser than a real level control. Good for "shut Netflix up for a second," useless for "keep it playing softly under my music." If you want the finer version of this, we cover controlling a browser tab's volume versus the whole browser in a separate guide.

Option 3 — A per-app mixer (the real fix)

The reason none of the above lets you set Netflix quieter than your call is that macOS gives you one master output level and no per-app mixer. Windows has had the Volume Mixer — one slider per app — for years; macOS never shipped it. A dedicated per-app mixer adds that missing layer: it sits at the OS audio level and gives every running app its own volume in one place.

The catch specific to Netflix is that a per-app mixer sees your browser, not the streaming site. So it controls "Chrome" or "Safari," and if you have Netflix and a work doc making noise in the same browser, they move together. The clean setup — the one worth knowing — is to keep Netflix in a browser you don't use for anything else (say, Netflix always in Safari, work always in Chrome). Then the mixer's "Safari" channel is your Netflix channel, and you can pin it to any level you like against everything else on the Mac.

Background Music (free and open source) and SoundSource (from Rogue Amoeba, $49 one-time) both do genuine per-app volume and are worth your time. They differ from Fader less in whether they can set a browser's level and more in how fast you reach the control — which, for something as twitchy as ducking Netflix when a call rings, is the whole game.

Why the keyboard is the fast fix for Netflix

Netflix volume is a "right now" adjustment. A loud trailer starts, someone messages you, the dialogue in a scene drops and you want to nudge it up. A menu-bar mixer means: reach for the menu bar, click the icon, find the browser row, drag the slider, dismiss the panel. That's five moves for a change you make a dozen times an evening.

Fader's bet is that the fastest controller you already own is your keyboard. You hit a toggle hotkey, the keyboard becomes a mixer — a column of letter keys is your browser channel — and you ride Netflix down or mute it with a keystroke, without leaving the show or the call. Bind a per-app mute key and "silence Netflix" is one press from anywhere. If you also keep music or a browser tab of music going, the same idea covers controlling other browser audio like YouTube independently.

Bottom line

To just make Netflix quieter, use the slider in its own player — free, instant, Netflix-only. To silence it when a call lands, mute the tab. But because Netflix is browser-only and macOS has no per-app mixer, neither can hold Netflix at a set level below your other apps. For that you need a per-app mixer, ideally with Netflix parked in its own browser. Background Music and SoundSource do it well; if reaching the control in a single keystroke is what you care about, that's exactly what Fader is built for.
