How to Use Dark Reader: Enable Dark Mode on Any Website

Dark Reader is the most popular dark mode extension for Chrome, with over 7 million users. Unlike browser-level dark mode settings that only affect Chrome's own UI, Dark Reader applies a smart dark theme to every website you visit — no matter how the site was designed. This guide covers everything you need to know to set it up and customize it.

What Is Dark Reader?

Dark Reader is a free, open-source Chrome extension that inverts and adjusts the colors of any webpage to create a dark theme. It uses smart algorithms to preserve images, maintain readability, and avoid the harsh color shifts that simple CSS inversion produces. It works on Gmail, Twitter, Reddit, Wikipedia, news sites, and virtually every other webpage.

How to Install Dark Reader

Visit the Dark Reader page on Unscart or search for "Dark Reader" on the Chrome Web Store.
Click "Add to Chrome" and confirm the installation.
The Dark Reader icon (a sun/moon) appears in your Chrome toolbar.
Dark mode is immediately enabled on all websites — no configuration required to start.

The Dark Reader Control Panel

Click the Dark Reader icon in your toolbar to open the control panel. Here's what each option does:

On/Off Toggle

The large toggle at the top enables or disables Dark Reader globally. Use the small dropdown next to it to toggle Dark Reader for just the current site or just the current URL, leaving all other sites unaffected.

Filter Mode vs. Dynamic Mode

Filter: Uses CSS filters to invert colors. Fast but can distort images and videos.
Filter+: A smarter version of Filter that preserves more colors.
Dynamic: Analyzes the page's CSS and generates a true dark theme. Best quality but slightly slower on complex pages.
Static: Applies a simple static dark stylesheet. Fast but less precise.

For most users, Dynamic mode produces the best results. Switch to Filter mode on slow pages if performance is an issue.

Brightness, Contrast, and Grayscale

Use the sliders to adjust the intensity of the dark theme. A brightness of 90 and contrast of 90 gives a slightly softer dark theme that's easier on the eyes for long reading sessions. The Grayscale slider desaturates colors — useful for reducing visual noise.

Sepia Tint

Adding a small amount of sepia gives the dark theme a warm, paper-like tone. Many users prefer a sepia value of 10–20% for evening reading as it reduces the blue light that affects sleep.

Scheduling Dark Mode

Dark Reader can switch dark mode on and off automatically based on a schedule or your system's light/dark mode setting:

Open the Dark Reader control panel.
Click the "Time" tab at the top of the panel.
Choose "System" to follow your OS light/dark mode, or "Custom" to set specific on/off times.

With the System setting, Dark Reader activates automatically at sunset (if your OS uses automatic dark mode) and deactivates at sunrise.

Site List — Enabling or Disabling for Specific Sites

Some websites already have well-designed dark modes, or Dark Reader's algorithm doesn't work well on specific sites. Use the Site List to control this:

Open the control panel and click the "Site List" tab.
Add sites where Dark Reader should be disabled to the "Not Invert Listed" column.
Add sites where Dark Reader should always be enabled (even if globally off) to the "Invert Listed" column.

Dark Reader on YouTube and Google

Both YouTube and Google have their own native dark modes. You can choose to let Dark Reader handle them, or disable Dark Reader on those sites and use the native setting. Native dark modes are usually better optimized for their respective site's video players and complex UI elements.

Performance Tips

Use Filter mode on media-heavy pages like video sites to reduce CPU usage.
Add frequently visited sites to the site list with their optimal mode already set.
Dark Reader uses very little memory — it has minimal impact on Chrome's overall performance.

Conclusion

Dark Reader is the simplest and most effective way to browse the entire web in dark mode. Install it once, tweak the brightness to your preference, and your eyes will thank you during every late-night browsing session. Explore more accessibility and comfort extensions in the Unscart directory.
