Focus Mode Pro
Instantly dim any website to reduce eye strain. Free, private, and lightweight. Also works on Microsoft Edge, Brave, and Opera.
A smarter way to reduce screen brightness
Focus Mode Pro 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.

Frequently asked questions
Is Focus Mode Pro free to use?
Yes. Focus Mode Pro is completely free to download and use. There are no hidden subscriptions or paywalls.
Why does the extension need permission to "read and change data on all websites"?
This sounds alarming, but it is a standard requirement for this type of tool. The extension needs permission to place the dark overlay on the page you are viewing. Without this permission, it cannot change the screen brightness. We do not read your emails, passwords, or browsing history.
Does it work on every website?
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://).
Can I turn it off for specific sites like YouTube?
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.
The extension is not working on a specific tab. What should I do?
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.
What browsers are supported?
Focus Mode Pro works on Google Chrome, Microsoft Edge, Brave, and Opera. Any Chromium based browser should be compatible.
Do you collect my browsing data?
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.
