Nocturn – Dark & Light Mode

Force any website into dark or light mode. Per-site memory. Images stay beautiful.

Tired of blinding white websites at 2am? Or dark sites that strain your eyes during the day? Nocturn puts you in control of every website's brightness — instantly, with one click. Most dark mode extensions blindly invert everything. Photos look like negatives. Logos turn neon. Nocturn is smarter — it forces dark or light mode on any site while automatically re-inverting images, videos, and photos so they always look exactly as intended. What Nocturn does: Force dark mode on any website — even ones that don't support it natively Force light mode on dark sites when you need clarity Set Auto mode to follow your system preference per site Remembers your choice for every site — set it once, forget it forever Images, videos, and photos stay true to color — no inverted weirdness
