# ImageScaleBy - ComfyUI Built-in Node Documentation

> Complete documentation for the ImageScaleBy node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The ImageScaleBy node is designed for upscaling images by a specified scale factor using various interpolation methods. It allows for the adjustment of the image size in a flexible manner, catering to different upscaling needs.

## Inputs

| Parameter        | Description                                                                                                                                         | Data Type      |
| ---------------- | --------------------------------------------------------------------------------------------------------------------------------------------------- | -------------- |
| `image`          | The input image to be upscaled. This parameter is crucial as it provides the base image that will undergo the upscaling process.                    | `IMAGE`        |
| `upscale_method` | Specifies the interpolation method to be used for upscaling. The choice of method can affect the quality and characteristics of the upscaled image. | COMBO\[STRING] |
| `scale_by`       | The factor by which the image will be upscaled. This determines the increase in size of the output image relative to the input image.               | `FLOAT`        |

## Outputs

| Parameter | Description                                                                                                                | Data Type |
| --------- | -------------------------------------------------------------------------------------------------------------------------- | --------- |
| `image`   | The upscaled image, which is larger than the input image according to the specified scale factor and interpolation method. | `IMAGE`   |
