Enable Dark Mode on YouTube on Desktop

Click your channel’s icon in the upper-right corner of the YouTube home page. From the drop-down menu, click “Appearance -> Dark Theme.” Setting it to “Device theme” can also be good if you want your theme adapting to your Windows theme.

Change Chrome Border to Dark Mode

Now your YouTube is dark and easy on the eyes, but you can probably see that the browser window is still glaring and bright. Whether you’re using Windows or Mac, you can fix this:

In Windows 10, right-click the desktop background -> Personalize -> Colors, then change “default app mode” to Dark.In macOS, go to “System Preferences -> General -> Appearance,” and click the Dark option.

Enable YouTube Dark Mode on Android/iOS

Enabling dark mode on YouTube for Android and iOS is similarly simple. It’s the same process on both platforms. Just open the YouTube app, then tap your profile icon at the top-right corner -> Settings -> General -> Appearance. In the Appearance pop-up, tap either “Dark theme” or “Use device theme” if you happen to use a dark theme on your given platform. Activating YouTube’s Night Mode will provide you with exactly what is suggested, as well as a few other developer features.
