ResizeImageMaskNode - ComfyUI Built-in Node Documentation

The Resize Image/Mask node provides multiple methods to change the dimensions of an input image or mask. It can scale by a multiplier, set specific dimensions, match the size of another input, or adjust based on pixel count, using various interpolation methods for quality.

Inputs

Parameter	Description	Data Type	Required	Range
`input`	The image or mask to be resized.	IMAGE or MASK	Yes	N/A
`resize_type`	The method used to determine the new size. The required parameters change based on the selected type.	COMBO	Yes	`SCALE_BY` `SCALE_DIMENSIONS` `SCALE_LONGER_DIMENSION` `SCALE_SHORTER_DIMENSION` `SCALE_WIDTH` `SCALE_HEIGHT` `SCALE_TOTAL_PIXELS` `MATCH_SIZE`
`multiplier`	The scaling factor. Required when `resize_type` is `SCALE_BY` (default: 1.00).	FLOAT	No	0.01 to 8.0
`width`	The target width in pixels. Required when `resize_type` is `SCALE_DIMENSIONS` or `SCALE_WIDTH` (default: 512).	INT	No	0 to 8192
`height`	The target height in pixels. Required when `resize_type` is `SCALE_DIMENSIONS` or `SCALE_HEIGHT` (default: 512).	INT	No	0 to 8192
`crop`	The cropping method to apply when dimensions don’t match the aspect ratio. Only available when `resize_type` is `SCALE_DIMENSIONS` or `MATCH_SIZE` (default: “center”).	COMBO	No	`"disabled"` `"center"`
`longer_size`	The target size for the longer side of the image. Required when `resize_type` is `SCALE_LONGER_DIMENSION` (default: 512).	INT	No	0 to 8192
`shorter_size`	The target size for the shorter side of the image. Required when `resize_type` is `SCALE_SHORTER_DIMENSION` (default: 512).	INT	No	0 to 8192
`megapixels`	The target total number of megapixels. Required when `resize_type` is `SCALE_TOTAL_PIXELS` (default: 1.0).	FLOAT	No	0.01 to 16.0
`match`	An image or mask whose dimensions the input will be resized to match. Required when `resize_type` is `MATCH_SIZE`.	IMAGE or MASK	No	N/A
`scale_method`	The interpolation algorithm used for scaling (default: “area”).	COMBO	Yes	`"nearest-exact"` `"bilinear"` `"area"` `"bicubic"` `"lanczos"`

Note: The crop parameter is only available and relevant when the resize_type is set to SCALE_DIMENSIONS or MATCH_SIZE. When using SCALE_WIDTH or SCALE_HEIGHT, the other dimension is automatically scaled to maintain the original aspect ratio.

Outputs
