Night Owl Pro — Dark Mode for Every Site

Turn any website dark. Adjustable brightness, contrast and warmth, with per-site control and a one-key toggle.

Bright websites at night are hard on your eyes. Night Owl Pro fixes that by bringing a clean dark theme to every site you visit — not just the handful that ship their own. Open a page and it's already dark: light backgrounds become deep and easy to read, while your photos and videos stay looking normal. When a site doesn't suit dark mode, turn it off for that site in one tap. Everything else just works. WHY YOU'LL LIKE IT Works on virtually any website, automatically, the moment a page loads Photos, videos and artwork are preserved — only the page chrome goes dark Fine-tune it with Brightness, Contrast and Warmth sliders until it's just right Per-site control: keep any site light, force it dark, or follow your default One-key toggle — press Alt+Shift+D to flip the current site without the mouse PRIVATE BY DESIGN Night Owl Pro does not collect, transmit, or sell any data. It never reads or sends the content of your pages. Your settings live on your own device, there's no tracking, no analytics, and no remote code. It asks only for the access it needs to style the pages you view. Give your eyes a break. Install Night Owl Pro and let the whole web go dark.
