There are two kinds of graphic files used on a computer - Raster (made up of pixels) and vector (made up of points/paths). A raster image uses a grid of individual square pixels where each pixel can be a different color or shade. Vector graphics use mathematical relationships between points and the paths connecting throughout the image.

    Wherever possible, it is suggested to use the vector format for all your logos, page layouts, font type, line art, cartoons, or illustrations and only use raster for photos or images with complex or non-uniform shading and effects.
