MagnificImageUpscalerPreciseV2Node - ComfyUI Built-in Node Documentation

The Magnific Image Upscale (Precise V2) node performs high-fidelity image upscaling with precise control over sharpness, grain, and detail enhancement. It processes images through an external API, supporting up to a maximum output resolution of 10060×10060 pixels. The node offers different processing styles and can automatically downscale the input if the requested output would exceed the maximum allowed size.

Inputs

Parameter	Description	Data Type	Required	Range
`image`	The input image to be upscaled. Exactly one image is required. Minimum dimensions are 160x160 pixels. The aspect ratio must be between 1:3 and 3:1.	IMAGE	Yes	-
`scale_factor`	The desired upscaling multiplier.	STRING	Yes	`"2x"` `"4x"` `"8x"` `"16x"`
`flavor`	Processing style: sublime for general use, photo for photographs, photo_denoiser for noisy photos.	STRING	Yes	`"sublime"` `"photo"` `"photo_denoiser"`
`sharpen`	Image sharpness intensity. Higher values increase edge definition and clarity. Default: 7.	INT	No	0 to 100
`smart_grain`	Intelligent grain/texture enhancement to prevent the image from looking too smooth or artificial. Default: 7.	INT	No	0 to 100
`ultra_detail`	Controls fine detail, textures, and micro-details added during upscaling. Default: 30.	INT	No	0 to 100
`auto_downscale`	Automatically downscale input image if output would exceed maximum resolution. Default: False.	BOOLEAN	No	-

Note: If auto_downscale is disabled and the requested output size (input dimensions × scale_factor) exceeds 10060x10060 pixels, the node will raise an error. When auto_downscale is enabled, the node will attempt to find an optimal scale factor that keeps quality loss minimal.
