A vector graphic is a computer-made image that is made up of points, lines, and curves that are based upon mathematical equations, rather than pixels.
Vector graphics can be scaled without losing resolution. They can be enlarged or reduced in size – but the file size will stay almost exactly the same.
Vector art is created using vector illustration software programs, such as Adobe Illustrator or Corel Draw. These programs use mathematic equations and geometric primitives (points, lines, and shapes) to create art that is clean, camera ready, and can be scaled infinitely, without any loss of quality or fidelity.
