ThresholdMask - ComfyUI Built-in Node Documentation

Complete documentation for the ThresholdMask node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The ThresholdMask node converts a mask to a binary mask by applying a threshold value. It compares each pixel in the input mask against the specified threshold value and creates a new mask where pixels above the threshold become 1 (white) and pixels below or equal to the threshold become 0 (black).

Inputs

Parameter	Description	Data Type	Required	Range
mask	The input mask to be processed	MASK	Yes	-
value	The threshold value for binarization (default: 0.5)	FLOAT	Yes	0.0 - 1.0

Outputs

Output Name	Description	Data Type
mask	The resulting binary mask after thresholding	MASK
