About this tool
The Darken Image tool applies a darkness filter to images with adjustable intensity. Use the slider to control how strongly the image is darkened, preview the result in real time, and download the modified image as a PNG when you're satisfied.
Darkening images is a common design technique. Adding a dark overlay to a hero image makes white text readable against a busy background. Reducing brightness on ambient images prevents them from competing with foreground content. Creating night-mode or dramatic aesthetic effects for social media and presentations are other common applications.
The effect is achieved by blending the original image with a black overlay at the specified opacity, implemented with the HTML5 Canvas API entirely in your browser. No data is sent to any server. The adjustment is non-destructive in the sense that your original file is unchanged — the downloaded image is a new file.
