Encapsulated PostScript

What is EPS?

Encapsulated PostScript (EPS) is a graphics file format based on the PostScript page description language. EPS files can contain both vector and raster graphics and are designed to be embedded within other PostScript documents. The format has been widely used in professional publishing and printing industries for decades, though it's being gradually replaced by PDF in many workflows.
