DarkLens

Smart dark mode — 4 themes, force-dark, image-safe, per-site & schedule.

DarkLens is a professional dark mode extension that transforms the entire web into a comfortable, eye-friendly experience without altering the original design or layout of any website. Unlike basic dark mode tools that simply invert colors or slap a dark overlay on everything, DarkLens uses smart color rewriting technology. It analyzes each element individually, darkens light backgrounds to rich dark tones, and brightens dark text to readable light shades. Images, videos, photos, and graphics are never touched and always display in their original quality. WHAT MAKES DARKLENS DIFFERENT Most dark mode extensions ruin website layouts, break images, or make text unreadable. DarkLens is engineered to enhance readability while preserving the visual integrity of every page. Your browsing experience gets darker, not broken. CORE FEATURES Fine-Tune Filters — Independently adjust brightness, contrast, sepia tone, and grayscale to dial in exactly the look your eyes prefer. Every slider updates in real time. Smart Site Management — Run DarkLens in block list mode to activate it everywhere except the sites you choose, or switch to allow list mode to activate it only on specific sites. Toggle any site on or off with a single click directly from the popup. Per-Site Control — The current page hostname is always visible in the popup. Enable or disable dark mode for it instantly without typing anything. Auto Schedule — Set a From and To time to have DarkLens activate and deactivate automatically every day. Overnight ranges are fully supported. You never have to remember to turn it on at night. Smooth Transitions — Optional fade transitions make toggling dark mode feel polished rather than jarring. Broad Compatibility — DarkLens runs on virtually every website including single-page applications, dynamically loaded content, and sites with shadow DOM components. EXCLUDED WEBSITES DarkLens intentionally skips certain categories of websites where color accuracy is critical or a native dark theme is already present — including online code editors, coding playgrounds, data science notebooks, and media streaming platforms. This ensures those tools work exactly as intended. You can still manually add any excluded site to your allow list if you prefer dark mode there. PRIVACY DarkLens does not collect, transmit, or store any personal data. All settings are saved locally in your browser using Chrome's built-in sync storage. No account required. No tracking.
