About this extension
🌙 Lights Out turns bright websites into comfortable dark pages in one click.
✨ Smart mode remaps each element’s colors and keeps every site’s brand hues, so pages look designed for the dark instead of inverted.
⚡ Simple mode inverts the whole page for maximum speed on sites that resist Smart mode.
🎚 Fine-tune brightness, contrast, and warmth to match your eyes.
🖼 Images and photos stay untouched by default, with an optional dim setting.
🛡 Keep favorite sites light with an allowlist that covers subdomains too.
⌨ Toggle instantly with Alt + Shift + L.
🎨 Modern settings with a dark or light interface.
🔒 Private by design: no data collected, no accounts, no tracking, no remote code.
Works on news sites, docs, forums, dashboards, and more. Sites that already support dark mode are left alone.
Found a page that looks off? Open the popup, switch to Simple mode, or add the site to your keep-light list. Feedback is always welcome.
