A to Z of Design: V is for vector

You may have had a designer ask you for a vector version of your logo and wondered: “What the heck is that?”

Vector images are made up of points, lines and curves, so they can be scaled to virtually any size without losing quality or becoming pixelated or blurry; they maintain their high resolution.

Conversely, raster images are created from a grid of pixels (if you’ve ever accidentally zoomed in really close on an image, you’ve seen this). So when you enlarge a small raster image, you begin to see those pixels and hard edges. Enlarging too much will cause the image to appear low resolution.

Vector images are generally created in Adobe Illustrator and have a file extension of .eps or .ai. Raster images are generally created in a program like Photoshop and can have a file extension of .eps, .tif, .jpg or .png.
