# ImageScaleToTotalPixels - ComfyUI Built-in Node Documentation

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

The ImageScaleToTotalPixels node is designed for resizing images to a specified total number of pixels while maintaining the aspect ratio. It provides various methods for upscaling the image to achieve the desired pixel count.

## Inputs

| Parameter        | Data Type      | Description                                                                                                   |
| ---------------- | -------------- | ------------------------------------------------------------------------------------------------------------- |
| `image`          | `IMAGE`        | The input image to be upscaled to the specified total number of pixels.                                       |
| `upscale_method` | COMBO\[STRING] | The method used for upscaling the image. It affects the quality and characteristics of the upscaled image.    |
| `megapixels`     | `FLOAT`        | The target size of the image in megapixels. This determines the total number of pixels in the upscaled image. |

## Outputs

| Parameter | Data Type | Description                                                                                          |
| --------- | --------- | ---------------------------------------------------------------------------------------------------- |
| `image`   | `IMAGE`   | The upscaled image with the specified total number of pixels, maintaining the original aspect ratio. |
