What is the difference between vector and raster formats when downloading and using QR codes?

The main difference between vector and raster graphics is that vector graphics are composed of paths, while raster graphics are composed of pixels. Vector graphics can be resized without loss of quality, which is ideal for printing. Vectors come in 4 file formats — .AI, .EPS (print use), .SVG (digital use) and .PDF. Raster graphics lose quality when resized. Examples of Raster formats include .GIF,.JPG,.PNG and .TIFF. For best results printing standard QR codes we recommend .EPS format. That said, if the QR code design is customized or includes tranparency, .SVG format should be used.

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.

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. 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.
