Upscale Image

class_type: ImageScale

Source repo

Resizes an image to specified dimensions using configurable interpolation methods (nearest, bilinear, bicubic, lanczos). Used for resolution changes, upscaling, and preparing images for further processing.

What It Does

ImageScale resizes images within the ComfyUI pipeline. It supports multiple interpolation methods that affect quality: nearest-neighbor (fast, pixelated), bilinear (smooth, some blur), bicubic (sharper), and lanczos (best quality for downscaling).

This node is commonly used in hi-res fix workflows (generate at low res, upscale, re-sample at higher res) and for preparing images to specific output dimensions.
