Focus Mode Professional is a Chrome extension that applies a customizable dark overlay to any website you visit. Unlike basic extensions that just invert colors and break images, Focus Mode Pro dims the background while keeping text and videos readable.
It runs entirely on your device. No accounts, no data collection, no tracking. Just cleaner, dimmer browsing whenever you need it.
Use the slider to choose the perfect brightness level for your environment. From a subtle tint to full dark mode.
Set it and forget it. The extension remembers your brightness settings and automatically applies them to new tabs.
Want full brightness for YouTube or Netflix? Check "Disable on this site" and Focus Mode will remember your preference automatically.
Toggle on or off instantly using Alt+Shift+F (or Option+Shift+F on Mac). No need to touch your mouse.
Runs 100% locally on your device. No browsing history tracked, no personal data collected, no ads injected. Ever.
Only 43KB in size. No bulky frameworks, no background processes. Zero impact on your browser performance.
Visit the Chrome Web Store and click "Add to Chrome." Confirm the installation when prompted.
Chrome hides new extensions by default. Click the puzzle piece icon in the top-right corner, find Focus Mode Pro, and click the pin icon. The crescent moon icon will stay visible in your toolbar.
Navigate to any website and click the moon icon. Click "Turn On" to instantly dim the screen. Or press Alt+Shift+F to toggle it instantly.

Yes. Focus Mode Pro is completely free to download and use. There are no hidden subscriptions or paywalls.
This sounds alarming, but it is a standard requirement for this type of tool. The extension needs permission to inject the dark overlay onto the page you are viewing. Without this permission, it cannot modify the screen brightness. We do not read your emails, passwords, or browsing history.
It works on 99% of websites, including major sites like Facebook, Wikipedia, and Google Docs. For security reasons, Chrome prevents extensions from running on the Chrome Web Store itself or internal browser settings pages (chrome://).
Yes. If you prefer to watch videos in full brightness, simply go to that website, open the Focus Mode menu, and check the box that says "Disable on this site." The extension will remember your preference automatically.
If you had the tab open before installing the extension, try refreshing the page (F5 or Command+R). This allows the extension to load properly on that page.
Focus Mode Pro works on Google Chrome, Microsoft Edge, Brave, and Opera. Any Chromium-based browser should be compatible.
No. Focus Mode Pro runs locally on your computer. Your settings are saved in your browser's local storage, and no data is ever sent to any external server.
Download Focus Mode Pro for free and start browsing without the glare.
