How to Change OneNote to Dark Mode: Night Vision in 3 Easy Steps

Late-night note-taking shouldn’t feel like staring into the sun. I made the switch to dark mode in OneNote last month and my eyes have thanked me every evening since.

It’s a one-toggle setting on desktop, but mobile and web versions hide it differently. The process takes under 2 minutes once you know where to look, and works across Windows, Mac, iOS, and Android.

You’ll get a sleek black canvas that’s easier on the eyes, saves battery on mobile, and makes your notes pop. No third-party apps or workarounds needed—just built-in functionality.

Fair warning: the setting doesn’t always sync immediately between devices. If it doesn’t, a quick app restart usually fixes it.

What Youll Need

Instructions

Here’s the simple process I use to switch to dark mode without any hassle.

Launch the OneNote application on your device. I always start from the desktop shortcut to avoid confusion with the web version, which has a slightly different interface. Look for the gear icon labeled Settings in the top-right corner of the window.

Click on Settings to reveal the dropdown menu. From there, select Options. This is where all the customization magic happens, including the theme settings you need to adjust.

In the Options menu, locate the Personalize your copy of Microsoft Office section. This is usually near the top of the list. Here, you’ll see a dropdown menu labeled Office Theme.

Click the dropdown and you’ll see several options: Colorful, Dark Gray, Black, and White. For a true dark mode experience, select Black. This applies a dark theme across the entire OneNote interface, reducing eye strain in low-light conditions.

After selecting the Black theme, click OK to save your changes. The application will briefly flicker as it applies the new theme. Wait 2-3 seconds until the interface updates completely—you’ll know it’s done when the background turns dark and the text becomes light gray or white.

If the changes don’t appear immediately, close and reopen OneNote. This forces the application to reload with your new theme settings. The dark mode should now be active across all your notebooks.

Open a notebook and check that the page background is dark with light text. If it’s not, revisit the Options menu to ensure the Black theme is selected. Some versions of OneNote may require a restart of the app to fully apply the theme.

For mobile users, the process is similar: open the app, tap your profile icon, select Settings, then choose Theme and pick Dark. The changes take effect immediately, so no restart is needed.

Tips and Common Mistakes

Small details can make this process even smoother and prevent common hiccups.

Desktop Shortcut Advantage: I always start from the desktop shortcut as mentioned in Step 1 to avoid confusion with the web version. The desktop app has a more consistent interface for theme changes, and you won’t accidentally end up in the online version which sometimes has different settings layouts.

Theme Selection Clarity: In Step 2, don’t overlook the difference between “Dark Gray” and “Black” options. While both are dark themes, the “Black” option provides the most complete dark mode experience with true black backgrounds, which is what you want for maximum eye strain reduction in low-light conditions.

Patience with Application: During Step 3, that 2-3 second wait is crucial. I’ve seen people panic when the screen flickers and immediately try to undo their changes. The application needs that brief moment to fully apply the new theme across all elements of the interface.

Verification Step Importance: Step 4 isn’t just a formality. I’ve had instances where the theme appeared to change but some notebooks retained their old appearance. That quick verification ensures you catch any partial applications before you start working, saving you from sudden bright screens later.
