Downscale/Upscale/Resize Images

Upscaling refers to the process when an image is resized without loss of quality or information. Similarly, if images are downscaled there are resized to a smaller size without loss of information. When an image is only resized (not upscaled or downscaled), the resolution of the image is increased or decreased with some loss of quality. References to information or loss of quality refer to details of the actual image like edges of objects, color, difference in texture, and so on.
