Raster files are images built from pixels — tiny colour squares that, in great quantity, can form highly detailed images such as photographs. The more pixels an image has, the higher quality it will be, and vice versa. The number of pixels in an image depends on the file type (for example, JPEG, PNG or GIF).

Vector files use mathematical equations, lines and curves with fixed points on a grid to produce an image. There are no pixels in a vector file. A vector file’s mathematical formulas capture shape, border, and fill colour to build an image. Because the mathematical formula recalibrates to any size, you can scale a vector image up or down without affecting its quality.
