EPS is an image file format developed by Adobe. The name is an abbreviation for Encapsulated PostScript. The format is accessible for reading and editing in most popular vector graphic editors (for example, in CorelDraw). EPS files can use images, text fragments, 2D elements of vector graphics. You can work with these files on Windows or Mac OS operating systems. This is a universal way to save data, but it does not save some settings for the printer, and there cannot be more than one page in one file.
PDF is short for Portable Document Format, which can be translated from English as “Portable Document Format”. It was developed by Adobe Systems for use by US federal authorities as a tool for storing working documents. This is a universal cross-platform format, which is now standard for electronic documents. It serves to convert text files (including photographs or other images) into electronic documents without any loss. To read PDF files you need special programs - Adobe (Acrobat) Reader, PDF-Viewer and others.
