Every feature in CtrlBright is designed with one goal: giving you perfect, effortless brightness control without ever getting in your way.
CtrlBright places a precision virtual overlay on top of your display. Drag the opacity slider to your perfect brightness level and pick any color for the overlay tint.
Fine-tune the overlay from fully transparent to deeply dimmed with a smooth slider.
Choose any overlay color — classic black, warm amber, or any custom hex color.
Instantly reset to full brightness with a single click or keyboard shortcut.
Save your favourite brightness and color settings as named profiles for quick switching.
Whether you're on a Zoom call, Google Meet, or Microsoft Teams — CtrlBright's dimmed overlay and control window stay active on your screen, but neither shows up in screenshots, recordings, or screen shares. Other tools capture everything, leaving your audience with a dark, blurred image.
CtrlBright stays hidden, so you stay in control.
Go beyond simple dimming with the Prismatic Effect — a dynamic rainbow colour-shift overlay that cycles across the visible spectrum. Perfect for ambiance, creative work, or just standing out.
Enable the startup toggle so CtrlBright launches automatically every time Windows boots. Your screen will always be at the right brightness from the moment you sit down.
Assign your own global keyboard shortcuts to control brightness without ever opening the app. Increase or decrease opacity, toggle effects, and switch profiles — all from the keyboard.
CtrlBright is engineered to have the smallest possible footprint. It uses minimal CPU and RAM so you never feel any performance impact — even on older hardware.
CtrlBright lives quietly in your Windows system tray. Right-click for instant access to brightness presets and settings, or double-click to open the full control panel.
Other brightness tools are clunky, capture-unsafe, or drain resources. CtrlBright does it right.
