Modern Dark Mode
Free Chrome extension that applies intelligent dark mode to every website. Reduce eye strain with smart CSS filters, scheduling, and per-site control.
Modern Dark Mode is a free Chrome extension that applies intelligent CSS filter inversion to any website, converting bright pages into comfortable dark themes. Unlike browser-native dark mode, it works on all websites and preserves images, videos, canvas elements, and SVGs in their original colors using a double-inversion technique. Features include scheduled activation with custom start/end times, per-site exclusion lists, adjustable brightness, contrast, sepia, and grayscale controls, and a keyboard shortcut (Alt+Shift+D) for instant toggling across all tabs. The extension is 100% local with zero data collection, no external servers, and no tracking.
