If we are using your logo in a design, whether website, brochure, trade show display or other materials, we need your logo in a usable file format. We need to be able to place it into the design as large or small as it needs to be, and still have it remain crisp and sharp.
This requirement rarely applies to images other than logos and sometimes illustrations. Most images are supplied in .jpg format, which is a so-called “raster” or “pixel” format. Logos need to be in .eps or .ai which are “vector” formats. This enables us to scale the image up or down in size without any loss of clarity, without it becoming fuzzy or developing jagged edges.
