What is the difference between vector and raster graphics?

The main difference between vector and raster graphics is that raster graphics are composed of pixels, while vector graphics are composed of paths. Vector graphics can be resized without loss of quality, which is ideal for printing stickers. Vectors come in 4 file formats — .AI, .EPS, .SVG and .PDF. Raster graphics like photos lose quality when resized. Examples of Raster formats include .GIF,.JPG,.PNG .PSD and .TIFF. For best results printing stickers, we recommend vector artwork for logos and illustrations and high-resolution photos.

Raster images are made of pixels. A pixel is a single point or the smallest single element in a display device. If you zoom in to a raster image you may start to see a lot of little tiny squares. Raster images are created with pixel-based programs or captured with a camera or scanner. A raster image has a specific number of pixels. When you enlarge the image file without changing the number of pixels, the image will look blurry. When you enlarge the file by adding more pixels, the pixels are added randomly throughout the image, rarely producing good results.

Vector images are mathematical calculations from one point to another that form lines and shapes. When you enlarge a vector graphic, the math formulas stay the same, rendering the same visual graphic no matter the size. Vector graphics can be scaled to any size without losing quality. Vector graphics are created with vector software and are common for graphics that will be used for logos, illustrations, and for use with printing processes such as printing stickers.
