EPS stands for “Encapsulated PostScript,” and it is a vector graphic. It is editable, resizable and can be sized up or down without losing quality, for both web and print.
In comparison, JPEGs are “Lower Resolution” formats that are used for websites, emails, presentations, and basically anything web-related. TIFFs are “Higher resolution” but still cannot be enlarged more than the original file size and are used when you creating brochures, corporate identity, or anything to be printed. With both a JPEG and TIFF and re-sizing will cause your logo to be unclear and blurry.
When you receive your final brand logos from any designer you should have a file with an extension of “.eps” (EPS) and “.ai” (Illustrator), both of which are vector files. The EPS can be resized for anything from as small as business cards to as large as tradeshow banner, without losing its clarity and integrity. The .ai Illustrator file is also critical in case you ever need to have your logo mark,
