RecraftReplaceBackgroundNode - ComfyUI Built-in Node Documentation

Replace background on image, based on provided prompt. This node uses the Recraft API to generate new backgrounds for your images according to your text description, allowing you to completely transform the background while keeping the main subject intact. Each image in the input batch is processed separately, and the results are combined into a single output batch.

Inputs

Parameter	Description	Data Type	Required	Range
`image`	The input image to process	IMAGE	Yes	-
`prompt`	Prompt for the image generation (default: empty)	STRING	Yes	-
`n`	The number of images to generate (default: 1)	INT	Yes	1-6
`seed`	Seed to determine if node should re-run; actual results are nondeterministic regardless of seed (default: 0)	INT	Yes	0-18446744073709551615
`recraft_style`	Optional style selection for the generated background. If not provided, defaults to “realistic_image” style	STYLEV3	No	-
`negative_prompt`	An optional text description of undesired elements on an image (default: empty)	STRING	No	-

Notes:

The seed parameter controls when the node re-executes but does not guarantee deterministic results due to the nature of the external API.
When recraft_style is not connected or left empty, the node falls back to the realistic_image style.
When negative_prompt is left empty, it is not sent with the request.

Outputs

Output Name	Description	Data Type
`IMAGE`	The generated image(s) with replaced background. For each input image, the number of generated results is determined by `n`.	IMAGE
