Control your display brightness in seconds

Brightness is a free macOS utility that makes changing your screen brightness fast and simple. Instead of navigating deep into System Preferences, you can adjust levels directly from the app for quick, on-the-fly changes that match your current surroundings.

Benefits and key characteristics

  • Uses very little system memory and CPU, so it won’t slow your Mac down.
  • Helps reduce eye fatigue during long work or reading sessions by letting you quickly lower brightness.
  • Designed for people who move between different lighting conditions and need immediate adjustments.
  • Features an uncluttered interface for straightforward control without a learning curve.

How to use it

Open the app, move the slider or use the provided keyboard/menubar controls to set the screen brightness you want, and close the app—changes apply immediately. The interface is intentionally minimal so you can make fast tweaks without interrupting your workflow.
