ImageQuantize - ComfyUI Built-in Node Documentation

The ImageQuantize node is designed to reduce the number of colors in an image to a specified number, optionally applying dithering techniques to maintain visual quality. This process is useful for creating palette-based images or reducing the color complexity for certain applications.

Inputs

Field	Data Type	Description
`image`	`IMAGE`	The input image tensor to be quantized. It affects the node’s execution by being the primary data upon which color reduction is performed.
`colors`	`INT`	Specifies the number of colors to reduce the image to. It directly influences the quantization process by determining the color palette size.
`dither`	COMBO[STRING]	Determines the dithering technique to be applied during quantization, affecting the visual quality and appearance of the output image.

Outputs

Field	Data Type	Description
`image`	`IMAGE`	The quantized version of the input image, with reduced color complexity and optionally dithered to maintain visual quality.
