EPSF is a graphics and text format developed in 1989 by Adobe for MS-DOS and Macintosh platforms. EPSF files can store bitmap and vector graphics, as well as text data. EPSF is a seldom used extension and has been in part replaced by its shorter version, EPS.

EPSF files can be opened with vector and raster graphics editors or word processors such as Microsoft Word, included in Office productivity software suite. Using these tools, EPSF files can be converted to more popular formats, for example, PDF or JPG.
