Dark Theme By Emrek

Dark mode for every website — lightweight, customizable, and completely private.

Dark Theme by emrek applies a beautiful dark mode to any website you visit. No account needed, no data collected, no network
requests — ever. Everything stays on your device.

FEATURES

Two Dark Modes
• Dark — Full inversion with pure black background. Maximum contrast, perfect for OLED screens.
• Soft — Gentle 85% inversion with dark gray tones. Easier on the eyes for long reading sessions.

Smart & Customizable
• Brightness & Contrast sliders — Fine-tune the look of any page (50–150% range).
• Per-site memory — Your preferences are saved for each website automatically.
• Keyboard shortcut (Alt+D) — Toggle dark mode instantly without opening the popup.
• Dark site detection — Automatically skips websites that already have a dark theme.

Media Preservation
• Images, videos, SVGs, and embedded content stay natural — no awkward color inversions on your photos or videos.

Site Manager
• View all your saved sites in one place. Toggle or remove individual site preferences with a single click.
