How to Enable Dark Mode in Chrome (Every Method)
3 min read · Updated 8/24/2026
Dark mode for the browser UI is built in, but darkening every website needs the right extension. Here are all the methods that work.
Darken the Browser Itself
1. Type chrome://flags in the address bar. 2. Search for Auto Dark Mode for Web Contents. 3. Set it to Enabled and relaunch Chrome.
Darken Every Website
The flag only works on some sites. For a consistent dark mode everywhere, install [Dark Reader](https://singletabbrowser.com/extension/dark-reader) — it converts any site to dark with adjustable contrast and filters.
Mobile
Android: turn on system dark mode and Chrome follows. iPhone: use the same flag via chrome://flags if available.
