# WanImageToImageApi - ComfyUI Built-in Node Documentation

> The Wan Image to Image node generates an image from one or two input images and a text prompt.

The Wan Image to Image node generates an image from one or two input images and a text prompt. It transforms your input images based on the description you provide, creating a new image that maintains the aspect ratio of your original input. The output image is fixed at 1.6 megapixels regardless of the input size.
