ImageBlur - ComfyUI Built-in Node Documentation

Complete documentation for the ImageBlur node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The ImageBlur node applies a Gaussian blur to an image, allowing for the softening of edges and reduction of detail and noise. It provides control over the intensity and spread of the blur through parameters.

Inputs

Field	Data Type	Description
image	IMAGE	The input image to be blurred. This is the primary target for the blur effect.
blur_radius	INT	Determines the radius of the blur effect. A larger radius results in a more pronounced blur.
sigma	FLOAT	Controls the spread of the blur. A higher sigma value means the blur will affect a wider area around each pixel.

Outputs

Field	Data Type	Description
image	IMAGE	The output is the blurred version of the input image, with the degree of blur determined by the input parameters.
