What is Ghostscript?

Ghostscript is the name of a set of software that provides:

• An interpreter for the PostScript (TM) language, with the ability to convert PostScript language files to many raster formats, view them on displays, and print them on printers that don't have PostScript language capability built in;
• An interpreter for Portable Document Format (PDF) files, with the same abilities;
• The ability to convert PostScript language files to PDF (with some limitations) and vice versa; and
• A set of C procedures (the Ghostscript library) that implement the graphics capabilities that appear as primitive operations in the PostScript language.

For further information read the Ghostscript documentation

There are three versions of Ghostscript currently available.

The current AFPL Ghostscript version is 8.54.

Artifex Ghostscript is an OEM version licensed commercially from Artifex Software.

AFPL Ghostscript is distributed with a license called the Aladdin Ghostscript Free Public License that allows free use, copying, and distribution by end users, but does not allow commercial distribution. AFPL Ghostscript was previously known as Aladdin Ghostscript.

GPL Ghostscript is distributed with the GNU General Public License, which allows free use, and free copying and redistribution under certain conditions (including, in some cases, commercial distribution). GPL Ghostscript versions are usually released shortly after the next AFPL Ghostscript version.
