Best Free System-Wide Dark Mode Extension for Chrome
Patrick Bushe · May 1, 2026
An extension can darken every website, but not Chrome itself or the rest of your computer.
Modern Dark Mode is free, needs no account and collects no data: its settings stay in your browser. Once installed it darkens every website you open in Chrome, and Alt+Shift+D turns it on or off in all tabs at once. To darken Chrome's own tabs and menus, and your other apps, turn on dark mode in Windows or macOS settings. It also can't change Chrome's internal pages or the Chrome Web Store, where extensions aren't allowed to run.
