SharePoint Dark Mode: How to Get It (2026)
If you have hunted through SharePoint settings for a dark-mode toggle and come up empty, you are not missing it — SharePoint Online on the web genuinely does not have one. Here is what actually works: the mobile app’s built-in dark theme, and a browser extension to force dark mode on the desktop site.
Microsoft ships dark mode in Word, Excel, Teams, and Outlook, but SharePoint Online in the browser has no dark-mode setting. Site owners can build a dark-themed site with custom branding, but as an everyday user you cannot flip a switch. There are two real paths.
Dark mode in the SharePoint mobile app
The SharePoint app for iPhone and Android does have a dark theme, and it follows your phone:
- Open the SharePoint app and tap your profile picture (top left).
- Tap Settings → Appearance.
- Choose Dark, or System default to match your phone’s theme.
Dark mode for SharePoint on the web (desktop)
Since there is no native option, the reliable fix is a browser extension that forces a dark theme onto the page. A good one detects SharePoint’s light background and regenerates it as dark — text, ribbons, lists, and document libraries included — without breaking layout.
Modern Dark Mode does this on any Chrome-based browser (Chrome, Edge, Brave). Install it, and SharePoint, along with every other site, goes dark. If a specific page looks off, you can whitelist it in one click.
What about a company-wide dark theme?
SharePoint administrators can apply custom themes to sites, but those are brand palettes, not a true user-controlled dark mode, and they only affect sites the admin owns. For a consistent dark experience across all SharePoint sites you visit, the browser-extension route is simpler and works everywhere.
Frequently asked questions
Does SharePoint Online have a dark mode setting?
No. As of 2026, SharePoint Online in the browser has no built-in dark-mode toggle for regular users. The SharePoint mobile app does have a dark theme, and on desktop you can force dark mode with a browser extension.
How do I turn on dark mode in the SharePoint app?
Open the SharePoint mobile app, tap your profile picture, then Settings > Appearance, and choose Dark (or System default to match your phone).
Will forcing dark mode break SharePoint?
A good dark-mode extension regenerates colors while preserving layout, so lists, libraries, and navigation stay usable. If one page looks wrong, whitelist just that page to keep it light.
Force dark mode on SharePoint and every other site
Microsoft never gave SharePoint on the web a dark mode. Modern Dark Mode adds one — and darkens every other site you use — right inside Chrome or Edge.
