Force any site into dark mode with Microsoft Edge — no extension required

Developer July 13, 2026No Comments

Microsoft Edge may soon let you force any website into dark mode. The option is one of several features in testing that are part of “Web Remix” within Edge.

Web Remix allows you to customize the look of a webpage. With a few clicks, you can change a page’s color, font size, and toggle it to dark mode.

But the feature is about more than appearances. Web Remix can convert prices that appear on a page to local currency, summarize a page, or simplify a long article.

Here’s what you can do with Web Remix, according to Microsoft:

Simplify a long article for easier reading
Add a summary to a detailed page
Turn a recipe into a shopping list
Convert prices to your local currency
Update the appearance of a webpage

Web Remix runs locally and functions similarly to Read mode in that you can click a button in the address bar to enable it or disable it.

Since this feature is in preview testing, there’s always a chance that it does not ship. Just last week, I covered the development of a great Microsoft Teams feature being paused while in preview.

You can enable Web Remix in Edge Canary by enabling the “Web Remix” and “Web Remix Internals” flags.

You can use Web Remix to force any website into dark mode, even if the site does not support the feature natively. However, the results will not be perfect. Converting a site to dark mode is more complex than it may appear, since there are many elements that need to remain unchanged.

Leo Varela, who spotted the feature on Edge, was kind enough to show Windows Central swapped to dark mode through Web Remix. The feature does an okay job, though I’d argue it was too aggressive in inverting certain elements. For example, the social media icons and the home bar should not be changed to black and grey, respectively.

The reason extensions like Dark Reader and Dark Mode – Night Eye cost money for full functionality is that converting sites to dark mode requires fine controls and nuance. Those extensions and similar extensions on other platforms let you customize dark mode and give more control than Web Remix.

But for a free tool that’s still in early testing, Web Remix does a nice job. Its other features are a nice bonus as well. But I’ve been obsessed with dark mode since the days of Windows Phone, so I care most about that.
