What is Dark Reader?
Dark Reader is a browser extension that creates dark themes for every website on the fly. It intelligently inverts colors, adjusts contrast, and preserves images so you get a comfortable reading experience in low-light environments without waiting for sites to add native dark mode support.
How It Works
Install Dark Reader and it activates on every website automatically
Choose Filter or Dynamic mode for color inversion accuracy
Adjust brightness, contrast, and sepia per-site or globally
Dark Reader analyzes each website's CSS and dynamically generates a dark stylesheet. It processes colors, backgrounds, borders, and shadows while preserving image integrity. You can choose between 'Filter' mode (fast, CSS filter-based) or 'Dynamic' mode (smarter, per-element analysis) depending on your preference.
Key Features
Why People Use Dark Reader
