How it works

Bunny Optimizer provides two complementary filters for controlling image sharpness: Sharpen: Enhances edge definition and detail by increasing contrast along edges. Makes images appear crisper and more defined. Blur: Softens the image by reducing detail and creating a smooth, out-of-focus effect. Higher values produce stronger blur.

​
Usage
