Pixels are tiny coloured squares on a screen and when there are a lot of them together, they make up a pixel based graphic. ... Vector graphics are mapped out using mathematical equations which calculate where the edges of the shapes sit in relation to one
Inherently, vector-based graphics are more malleable than raster images — thus, they are much more versatile, flexible and easy to use. The most obvious advantage of vector images over raster graphics is that vector images are quickly and perfectly scalable. There is no upper or lower limit for sizing vector images.
