Features & Capabilities

Dimmer is a Chrome extension designed to reduce eye strain by dimming the brightness of web pages. Even if you use dark mode, bright images and videos can cause discomfort. This addon overlays a dark filter on the entire page, making viewing more comfortable.

Key features include toggling dim mode globally for all tabs or individually for the active tab via customizable keyboard shortcuts (Ctrl + Alt + N / Ctrl + Alt + B on Windows/Linux, ⌘ + ⌥ + N / ⌘ + ⌥ + B on Mac). Users can set sharing options so that dim states apply across all 'All tabs' set pages or only affect individual tabs. Default tab behaviors and switching between shared or individual dim states are also supported, ensuring flexibility tailored to your browsing habits.

User Reviews

Users appreciate Dimmer for its straightforward brightness dimming without color inversion, simple slider control, and handy keyboard shortcuts. It significantly helps reduce eye strain and reflections, enhancing user comfort. However, multiple users report the need to reactivate the dimming on new pages, the dim button's pop-up not closing automatically, and incompatibility with PDF viewing in-browser as common issues.
Pros
  • Effectively dims screen brightness without inverting colors.
  • Simple and intuitive interface with a slider for brightness control.
  • Keyboard shortcut support for easy toggling.
  • Enhances comfort during video calls and reduces eye strain.
  • No intrusive data requirements; privacy-friendly.
Cons
  • Requires activation on each new page; lacks persistent state.
  • Dim button popup doesn't close automatically after use.
  • Does not work on PDFs viewed within the browser.

Is dimmer Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

dimmer requires a few sensitive permissions. Exercise caution before installing.
