Why Turn Off the Lights
The Most Complete Chrome Dark Mode Solution Available
When people search for Chrome dark mode, they usually want one thing: every website they visit to be dark, not just Chrome's own browser interface. Turn Off the Lights delivers exactly this.
Dark Mode for Every Website in Chrome
Chrome's built-in dark mode only changes the browser's own UI. Turn Off the Lights goes further — it applies a true Night Mode to every single website you visit in Chrome, including YouTube, Reddit, Wikipedia, Google Search, Gmail, and beyond.
True Black Mode for OLED Displays
If your laptop, monitor, or display uses an OLED panel, Turn Off the Lights offers a true-black Chrome dark mode that sets backgrounds to pure #000000. On OLED, black pixels are literally off — saving real battery power and delivering deeper contrast.
Smart Chrome Dark Mode That Adapts
The extension automatically detects when a website already supports dark mode and skips applying a second overlay. For sites without native dark support, it intelligently converts white backgrounds to your chosen dark color while keeping images visible and text readable.
Open Source, Private, and Free — Always
Turn Off the Lights collects no personal data, displays no advertising, and charges nothing. The extension is fully open-source under the GNU General Public License Version 2 (GPLv2), with its complete source code available on GitHub for anyone to inspect. It has been in continuous development since 2009 and remains one of the most trusted browser extensions available, with millions of active users across all major browsers. Stefan Van Damme is the solo developer and has maintained the extension with monthly updates for over 15 years.
