Umbra - Screen Dimmer

Adjust Page Brightness

Control your browser's global screen brightness to use sites that do not support the native dark theme This extension reduces or increases the screen brightness level for both daytime and nighttime periods based on user-defined values. It helps the websites that do not support the native dark theme. Also, it can increase the brightness of websites that are too dark. It reduces the eyestrain while reading documents online when dark mode is not supported. The extension offers two different values for daytime and nighttime duration to enhance usability. Features: 1. Control the darkness level of all websites or just a single hostname 2. You can increase or decrease the brightness level of a website 3. Supports keyboard shortcuts for every action. 4. You can disable the extension on a single website or entirely 5. Control the brightness level from 0% (completely dark) to 120% (20% brighter than the original) 6. Supports two different methods to decrease the brightness level. Notes: 1. By setting the brightness level to 100%, the extension does not affect browser tabs (does not inject any CSS styling) 2. It is recommended to configure the start time for both daytime and nighttime. By default, daytime starts at 08:00, and nighttime starts at 19:00. 3. By adding a website to the exception list, brightness control is turned off for this website. You can use this feature to turn off the extension on websites that support native dark mode. 4. This extension does not reduce the screen brightness when printing a webpage. There is a CSS selector that only affects "screen" type displays. What is the difference between this extension and other dark mode extensions (e.g. "Dark Reader™" or "Turn Off the Lights™" (I do not own these two extensions))? These extensions manipulate the styling of all elements by using custom stylesheets. They convert the light theme to dark. This extension only injects a filter to reduce or increase the original brighness. So it does not perform any resource-intensive operations and does not alter the website's styling.

Brightness Control

Control brightness of Page with a simple slider. Modern monitors can blast out more light than a desk lamp, yet almost every site assumes you are working in the same lighting conditions all day. Open a news page at midnight, and you are greeted by a blinding white wall; load a dimly-lit design portfolio at noon, and the images look muddy. Brightness Control fixes both problems with one simple, privacy-respecting slider that lives in your toolbar. Live brightness dial (30–150 %) Drag once, see the whole page change instantly—no reloads, no flicker. One-tap reset A dedicated button snaps the filter back to the natural 100 % state. Reduce fatigue and headaches A 2024 study in Applied Ergonomics found that lowering on-screen luminance by just 20 % in dark rooms cut self-reported eye strain by half. Instead of hunting for each site’s dark-mode toggle (if it exists at all), Adjust Page Brightness gives you a universal dimmer. Improve battery life on OLED laptops OLED pixels draw power roughly in proportion to their brightness. Dimming a page from 100 % to 60 % saves real watt-hours without throttling your CPU or disabling extensions. Enhance readability outdoors Graphic designers often dark-theme their portfolios, which look fabulous in a studio but invisible on a sunny café patio. With one slider you can push brightness to 140 % and keep every detail visible without squinting.

Adjust Page Brightness offers a rapid assistive technology layer that complements screen readers and high-contrast extensions.
