A vector file is a graphic that is made up of nodes, shapes & paths (not pixels). Vector graphics can be scaled to any size without losing quality, and normally are very small in file size. Vector files are made with graphic design software such as Adobe Illustrator, Corel Draw, etc.
A raster file consists of pixels (little squares). Every photo or raster based graphic is made up of pixels and the resolution of images are measured in ppi (pixels per inch) or dpi (printed dots per inch). The higher the ppi or dpi and larger dimensions for your image or design the better it will print.
Our graphic designers can vectorize your logo or design if you need a file in a more scalable format.
