It is the process of changing the image dimensions. This process typically involves modifying the number of pixels in the image. You can make an image larger (upscaling) or smaller (downscaling).

Resizing tools recalculate the image data to fit into a new pixel grid. Well, this process can significantly affect the image quality when enlarging.
