✨ Key Features That Make Us Stand Out

Intelligent Dark Mode: Our advanced conversion logic applies a deep, natural dark theme to any website. We meticulously handle colours to ensure a professional look that respects the site's original design.

Media Integrity: Unlike basic dark mode extensions, we guarantee that images, videos, logos, and GIFs retain their original brightness and colour. Your media will never look inverted or washed out.

Multiple Themes: Beyond Dark, choose from other stylish themes:

Milk: A soft, warm, light-on-dark theme for a cozy feel.

Dark Blue: A cool, modern dark theme with blue undertones.

Global & Per-Site Control: Effortlessly toggle themes globally, or set a specific theme for individual websites (Whitelisting).

Blazing Fast Shortcuts: Apply or reset any theme instantly with custom, memorable keyboard shortcuts:

Dark Mode: Ctrl + Shift + D

Milk Theme: Ctrl + Shift + M

Dark Blue: Ctrl + Shift + B

Reset Theme: Ctrl + Shift + R

Performance First: Built for speed. Our code is optimized to ensure zero slow-down on web pages.
