Vector graphics differ from raster graphics primarily because they can be scaled without losing quality. This is due to the fundamental way vector graphics are created. Vector graphics are composed of mathematical equations that define shapes, lines, and colors, rather than relying on a grid of pixels like raster graphics do. When you scale a vector graphic up or down, the mathematical equations simply adjust to maintain the integrity and sharpness of the image, regardless of size. This makes vector graphics ideal for designs that need to be resized, such as logos, typography, and illustrations.

In contrast, raster graphics are made up of a specific number of pixels. When these images are enlarged beyond their original resolution, they can become pixelated and lose detail, as the individual pixels become more visible. Vector graphics also provide greater flexibility for editing and manipulating shapes, giving designers more control over their work. Thus, the ability to be scaled indefinitely while preserving quality is a defining characteristic that sets vector graphics apart from raster graphics.
