Dark mode for every website on Mac

Why websites stay white on a dark Mac

In System Settings › Appearance, choosing Dark darkens Safari’s toolbar and tells websites you prefer dark colors. Only websites built with a dark theme listen. Most pages still open bright white, which is hardest on the eyes in a dim room.

Make every website dark with Dimlight

1. Download Dimlight from the Mac App Store. It’s free, and the same download works on iPhone and iPad.
2. Open the Dimlight app and click Open Safari Settings. Or, in Safari, choose Safari › Settings › Extensions.
3. Select the checkbox next to Dimlight.
4. Click Edit Websites… and set Other Websites to Allow.
5. Reload any open pages. They’re dark.

Use “Always Allow on Every Website”. If Safari asks for permission on a website, “Allow for One Day” switches Dimlight off tomorrow. And Private Browsing windows need their own permission: turn on Allow in Private Browsing in the same Extensions settings.

Choose, website by website

Click the Dimlight button in Safari’s toolbar to choose Auto, Always dark or Off for the website you’re on, pause Dimlight for an hour, or switch it off everywhere. The gear button opens Dimlight Settings, with five styles, background and text contrast sliders, and a list of every website you’ve set.

Auto is right for almost every website: when a site has its own dark theme, Dimlight uses it, so the page looks the way its designers made it. Photos and videos are never filtered.

Match your Mac’s schedule

Set Appearance to Auto in System Settings, so your Mac goes dark at sunset. Then choose “Only when my device is in Dark Mode” in Dimlight Settings, and websites follow along.
