HitPawGeneralImageEnhance - ComfyUI Built-in Node Documentation

This node enhances low-resolution images by upscaling them to super-resolution, removing artifacts and noise. It uses an external API to process the image and can automatically adjust the input size to stay within processing limits. 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.
