HitPawGeneralImageEnhance - ComfyUI Built-in Node Documentation

This node enhances low-resolution images by upscaling them to super-resolution while removing artifacts and noise.

This node enhances low-resolution images by upscaling them to super-resolution while removing artifacts and noise. It sends the image to an external API for processing, and it can automatically adjust the input size to stay within the allowed output limit. The maximum allowed output size is 32 megapixels.

Inputs

Parameter	Description	Data Type	Required	Range
model	The enhancement model to use. The generative_portrait model is optimized for portraits, while generative is a general-purpose model.	COMBO	Yes	"generative_portrait" "generative"
image	The input image to be enhanced.	IMAGE	Yes	-
upscale_factor	The factor by which to upscale the image’s dimensions. A factor of 1 means no upscaling, 2 doubles the dimensions, and 4 quadruples them.	COMBO	Yes	1 2 4
auto_downscale	Automatically downscale input image if output would exceed the limit. (default: False)	BOOLEAN	No	-

Note: The node raises an error if the calculated output size (input width × upscale_factor × input height × upscale_factor) exceeds 32,000,000 pixels (32MP) and auto_downscale is disabled. When auto_downscale is enabled, the node automatically reduces the input image size or the upscale factor (or both) so the output fits within the 32MP limit. The selected model and upscale_factor are combined into the model name sent to the service.

Outputs

Output Name	Description	Data Type
image	The enhanced and upscaled output image.	IMAGE
