Best dark mode Chrome extensions

A dark mode Chrome extension applies a dark theme to websites that don't offer one natively, reducing screen brightness and glare. Our top pick is Dark Reader: it is free, works on nearly every website by inverting or recoloring pages, and lets you adjust brightness, contrast and per-site settings.

Many sites, including Amazon, still don't offer a built-in dark mode, so the page stays bright white regardless of your system theme. A dark mode extension works around this by analyzing the page and repainting it with dark backgrounds and light text, which can help in low light or simply match your preference.

How dark mode extensions work

Dark Reader and similar extensions analyze a page's colors in real time and invert or recolor them, rather than relying on the site having its own dark theme. This means it works on almost any website, including ones that never added dark mode themselves, though occasional pages with unusual styling can render oddly.

Getting dark mode on Amazon and other bright sites

Amazon does not offer an official dark mode as of now, so a browser extension is the only way to darken it. Dark Reader can apply dark mode to Amazon and thousands of other sites automatically, and you can toggle it off per site if a particular page looks better in its original colors.

Adjusting brightness and contrast per site

A good dark mode extension lets you fine-tune brightness, contrast and sepia filters, and set different preferences for different websites. This matters because a one-size setting can make some sites too dim or wash out images, so per-site adjustment keeps text readable without over-darkening photos.

Best dark mode Chrome extensions: FAQs

What is the best dark mode extension for Chrome?

Dark Reader is our top pick because it is free and works on nearly every website by recoloring the page in real time. It also lets you adjust brightness, contrast and settings per site.

How do I get dark mode on Amazon in Chrome?

Amazon does not offer a built-in dark mode, so install a dark mode extension such as Dark Reader, which applies a dark theme to Amazon and most other sites automatically.

Does dark mode extension work on every website?

Most dark mode extensions work on the majority of websites by analyzing and recoloring the page, but sites with unusual styling or embedded images can occasionally render oddly. You can typically toggle it off for a specific site.

Can I set different dark mode settings for different sites?

Yes, most dark mode extensions, including Dark Reader, let you customize brightness, contrast and enable or disable dark mode separately for each website you visit.

Does a dark mode extension save battery?

On devices with OLED screens, darker pixels use less power, so dark mode can modestly reduce battery use. On standard LCD screens, the battery savings are minimal since the backlight stays constant.

Why does dark mode make some images look inverted?

Extensions that invert colors to create dark mode can accidentally invert photos and images too. Better extensions like Dark Reader detect images and leave them in their original colors instead of inverting everything.

Is there a free dark mode extension for Chrome?

Yes, Dark Reader is free and does not require an account to use. Most dark mode extensions are free since the underlying feature is straightforward to build.

Does dark mode extension work in Edge and Brave too?

Yes, dark mode extensions built for the Chrome Web Store, including Dark Reader, generally install and work on Chromium-based browsers such as Edge and Brave.

How is a dark mode extension different from Chrome's system dark theme?

Chrome's system dark theme only changes the browser's own menus and toolbar, not the content of websites. A dark mode extension changes how the actual web pages look, since most sites control their own page colors.

Can dark mode extensions cause a website to load slower?

There can be a small delay while the extension analyzes and recolors a page's colors, though it is usually unnoticeable. Complex pages with many images may take marginally longer to finish applying the dark theme.
