Vector files are those produced by vector graphics software packages like CorelDRAW, Macromedia Freehand, or Adobe Illustrator. You may scale, resize, and even modify the color or font of a vector file without sacrificing the quality or clarity of the image. In contrast to a bitmap format, this (see below). Professional designers or print firms are more likely to use vector files when your logo requires the finest reproduction quality. EPS (Encapsulated PostScript), AI (Adobe Illustrator), and CDR are popular vector file types (CorelDRAW).
