Dark mode for all websites · free Chrome dark mode extension Lights out. Every site.

You do not have to. Dark mode is on for every site from the moment the extension installs, including the tabs you already had open. The toolbar button turns it off again, and back on, for every tab at once.

It works on any http or https page, on local files opened from your disk, and on sites whose Content Security Policy blocks a page from adding styles to itself. Chrome does not let any extension touch its own pages, so chrome:// pages, the Chrome Web Store and other add-on stores always stay light.

No. The dark stylesheet is registered as a content script that runs before the page is first painted, so the page arrives dark instead of flashing white and then turning dark.

They are left alone. The extension samples the colour actually painted behind several points of the page and skips it when it is already dark, so a dark site is never inverted into a bright one.

No. Images, video, canvas, embeds and frames are flipped back to their real colours. Large photos set through CSS backgrounds are detected and flipped back too, which most invert-based extensions miss.

No. There are no settings and no popup: one button, on or off. The background settles at #121212 rather than pure black, because white text on pure black is harsher than any hand-built dark theme goes, and the same adjustment leaves white text exactly white.

It collects nothing. There are no accounts, no analytics and it never contacts a server. It asks for three permissions plus access to the pages it restyles: storage to remember whether the switch is on, scripting to deliver the stylesheet, and tabs to keep the toolbar icon showing the right state. The on or off state is kept in your own browser profile.

No. The switch is global: on or off everywhere. The one thing decided per page is whether it is already dark, and that is measured automatically rather than being a preference you set.

Yes. Chromebooks run Google Chrome, so you can install it from the Chrome Web Store. On a school or work Chromebook, your administrator decides which extensions are allowed.

Yes. It is free on the Chrome Web Store, with no account, no ads and no paid tier.

It depends which part you mean. Chrome's own setting, under Settings → Appearance → Mode, darkens the browser: tabs, menus and settings, but not the websites you open. To darken the pages themselves you need either Chrome's experimental "Auto Dark Mode for Web Contents" flag at chrome://flags/#enable-force-dark, or a dark mode extension like this one, which applies before the page paints and leaves already-dark sites alone.

We are not a neutral judge of that, so here is what to compare instead: does it apply before the first paint or flash white; does it detect sites that already ship a dark theme; does it restore photos, including ones set as CSS backgrounds; how many permissions does it ask for; and does it make network requests. Those five answers separate the careful ones from the rest, whichever you install.

Three names for the same thing. Chrome calls them extensions, Firefox calls them add-ons, and "dark mode plugin" is a habit carried over from browser plugins like Flash. This is a Chrome extension, installed from the Chrome Web Store.

Yes, for web pages. Night mode, dark theme, black mode and dark mode are four names for the same idea: light text on a dark background, and this extension gives websites that look. It is separate from Chrome's own dark theme, which darkens the browser's tabs and menus but not the pages you open.
