Dark 4 You

Automatically apply customizable dark mode to all websites with adjustable brightness, contrast, and more.

Dark 4 You – Advanced Dark Theme Extension for Chrome Dark 4 You is a modern, lightweight Chrome extension designed to apply a consistent, high-quality dark mode experience across the entire web. It automatically transforms bright websites into visually comfortable dark themes while preserving readability, layout structure, images, and video content. Built with modern Chrome Extension standards using Manifest V3, Dark 4 You delivers reliable performance, low memory usage, and seamless compatibility with today’s web technologies. Whether you browse at night, work long hours, or simply prefer dark interfaces, this extension provides complete control over how websites appear in your browser. Unlike basic color-inversion tools, Dark 4 You intelligently adapts page styles using CSS filters and dynamic stylesheet injection. This ensures text remains readable, UI elements stay usable, and media content such as images and videos is not distorted. What Dark 4 You Does Dark 4 You automatically detects and transforms light-themed websites into dark versions by adjusting background colors, text colors, borders, and UI elements. The extension runs silently in the background and applies changes in real time without requiring page reloads. The goal is simple. Reduce eye strain, improve focus, and create a consistent dark browsing experience across all websites. Core Features Overview Automatic Dark Mode for All Websites Once enabled, Dark 4 You applies dark mode to all websites you visit. There is no need to manually configure individual pages or domains unless you want custom behavior. The extension works across news websites, blogs and documentation, social media platforms, dashboards and admin panels, and web apps and SaaS tools. Intelligent Color Inversion Instead of blindly inverting every pixel, Dark 4 You selectively adjusts colors to maintain usability and visual balance. Light backgrounds are converted to dark shades, text colors are adjusted for optimal contrast, borders and UI components remain visible, and images, icons, and videos are preserved. This prevents common issues like inverted photos, unreadable buttons, or broken layouts. Customizable Appearance Controls Dark 4 You includes fine-grained controls that allow users to tailor the dark theme to their personal preferences. Brightness Control Adjust overall brightness to make pages darker or lighter depending on your environment. This is especially useful for night browsing or low-light conditions. Contrast Adjustment Fine-tune contrast levels to improve text clarity and visual separation between UI elements. Sepia Mode Apply a warm sepia tone for a softer reading experience, ideal for long reading sessions. Grayscale Mode Reduce color saturation or enable full grayscale mode for distraction-free browsing and accessibility support. All adjustments are applied instantly and saved automatically. Per-Website Dark Mode Control Not all websites look better in dark mode. Dark 4 You allows you to enable or disable dark mode on a per-site basis. You can toggle dark mode on or off for individual domains, remember preferences for each website, and automatically apply saved settings when revisiting a site. Global Enable and Disable Switch The global toggle allows you to enable dark mode across all websites, disable dark mode instantly with one click, and resume your saved settings at any time. No page reloads are required. Clean and Minimal Popup Interface Dark 4 You features a modern popup UI designed for simplicity and speed. The popup includes on and off toggles, slider controls for brightness and contrast, mode switches for sepia and grayscale, and a website-specific toggle. The interface is lightweight, responsive, and easy to use even for non-technical users. Performance and Efficiency Dark 4 You is designed to have minimal impact on system resources. It uses efficient CSS filters and injected stylesheets, avoids screenshots or canvas rendering, minimizes DOM manipulation, and runs only when needed. The extension scales well even on complex web pages. Privacy and Security Privacy is a core design principle. Dark 4 You does not track browsing activity, does not collect personal data, does not send data to external servers, and stores preferences locally using Chrome storage. All processing happens directly in your browser. Modern Chrome Extension Architecture Dark 4 You is built using the latest Chrome extension standards to ensure long-term compatibility and stability. It uses Manifest V3, content scripts for style injection, a background service worker for state management, popup HTML and JavaScript for UI controls, and the Chrome storage API for preference persistence. This architecture ensures compliance with Chrome Web Store policies and future browser updates. Use Cases Dark 4 You is ideal for night-time browsing, long reading sessions, developers and designers, students and researchers, professionals working with dashboards, and users with light sensitivity. It works across personal, educational, and professional workflows.
