OLED Night di Archline Labs

OLED Night turns website backgrounds true black while keeping text readable and images in their original colors. Made for OLED displays, and works on other screens too.

• Automatic dark mode, full recolor, deepen blacks only, invert, or off for each site.
• Per-site brightness, contrast, and optional image dimming.
• Schedule and Alt+Shift+D shortcut.
• Settings backup and a local broken-site report you can choose to share.

Free and open source. No ads, analytics, tracking, or developer servers. Website access is used to recolor pages locally. Settings use your browser’s sync storage.

Firefox desktop 142 or later. Some sites may need a different mode or to be turned off.
