BriaIncreaseResolution - ComfyUI Built-in Node Documentation - ComfyUI

Bria Increase Resolution upscales an input image by 2x or 4x using Bria’s image upscaling API, preserving the original content. It uploads the image, processes it on the Bria service, and returns the upscaled result as an image.

Inputs

Parameter	Description	Data Type	Required	Range
`image`	The input image to upscale.	IMAGE	Yes	Single image
`desired_increase`	Resolution multiplier. The output must fit within 8192 pixels on each side.	COMBO	Yes	”2" "4”
`auto_downscale`	Automatically lower the multiplier, and downscale the input image if that is still not enough, when the output would exceed the limit. (default: False)	BOOLEAN	Yes	True False
`moderation`	Moderation settings. When set to “true”, enables the `visual_input_moderation` and `visual_output_moderation` sub-options, both defaulting to False.	COMBO	Yes	”false" "true”

Notes:

The node enforces a maximum output side of 8192 pixels. If the selected multiplier would exceed this limit and auto_downscale is disabled, an error is raised. Enabling auto_downscale allows the node to automatically use a lower multiplier or downscale the input image instead.
Bria first enlarges the short side of the input image to at least 224 pixels before upscaling. Images that are too elongated may trigger an error asking to crop them to a squarer shape.

Outputs

Output Name	Description	Data Type
`IMAGE`	The upscaled image returned by the Bria API.	IMAGE
