comfyui-ihor-resize

A ComfyUI custom node that resizes images and masks together and returns the output dimensions.

Features

• Three resize modes
  • resize — stretch to an explicit width × height
  • longest side — scale so the longest edge equals the target, preserving aspect ratio
  • smallest side — scale so the shortest edge equals the target, preserving aspect ratio
• AI upscaling — connect any UPSCALE_MODEL to use a neural upscaler before the interpolation step
• Multiple interpolation methods — nearest-exact, bilinear, area, bicubic, lanczos
• Mask resize — the mask is resized to match the output image automatically
• In-node preview — toggle a live image preview directly inside the node
