Dark Reader is a third-party Internet browser extension that changes colors on a web page. When activated, it automatically applies a “dark theme” universally by changing light colors to dark and vice versa. Light backgrounds change to a dark grey, and black text changes to white. Also, users have the option to create a customized experience for every website. Adjustments include brightness level, contrast, grayscale, and sepia tones to reduce eye strain.

Dark Reader is available to use for free on Chrome, Firefox, and Safari browsers. To install Dark Reader, visit the extension marketplace for your preferred browser, or visit the official Dark Reader website.
