Vector graphics are sometimes also referred to as “draw graphics,” but they mean the same thing. The definition of vector graphics is complicated, but in a nutshell, a vector file is a type of graphic that uses mathematical algorithms, allowing the image to be scaled without loss of image quality. These images are easy to resize in a better quality graphic!
When you create an image in Adobe Illustrator (or in Freehand or CorelDRAW), you create a vector graphic. However, when you create an image in a program like Adobe Photoshop, you create a bitmap graphic, which is not a vectored format. A vector graphic retains its crispness at any magnification, but a bitmap graphic appears jagged when it’s enlarged.
