Ghostscript is a suite of software based on an interpreter for Adobe Systems' PostScript and Portable Document Format page description languages. Its main purposes are the rasterization or rendering of such page description language files, for the display or printing of document pages, the conversion between PostScript and PDF files. Ghostscript can be used as a raster image processor for raster computer printers—for instance, as an input filter of line printer daemon—or as the RIP engine behind PostScript and PDF viewers. Ghostscript can be used as a file format converter, such as PostScript to PDF converter; the ps2pdf conversion program, which comes with the ghostscript distribution, is described by its documentation as a "work-alike for nearly all the functionality of Adobe's Acrobat Distiller product". This converter is a thin wrapper around ghostscript's pdfwrite output device, which supports PDF/A-1 and PDF/A-2 as well as PDF/X-3 output. Ghostscript can serve as the back-end for PDF to raster image converter.

As it takes the form of a language interpreter, Ghostscript can be used as a general purpose programming environment. Ghostscript has been ported to many operating systems, including Unix-like systems, classic Mac OS, OpenVMS, Microsoft Windows, Plan 9, MS-DOS, FreeDOS, OS/2, Atari TOS and AmigaOS. Ghostscript was written by L. Peter Deutsch for the GNU Project, released under the GNU General Public License in 1986. Deutsch formed Aladdin Enterprises to dual-license Ghostscript under a proprietary license with an own development fork: "Aladdin Ghostscript" under the Aladdin Free Public License and "GNU Ghostscript" distributed with the GNU General Public License. With version 8.54 in 2006, both development branches were merged again, dual-licensed releases were still provided. Ghostscript is owned by Artifex Software and maintained by Artifex Software employees and the worldwide user community. According to Artifex, as of version 9.03, the commercial version of Ghostscript can no longer be distributed for commercial purposes without purchasing a license, though the GPL variant allows commercial distribution provided all code using it is released under the GPL.

Artifex's point of view on "aggregated software" was challenged in court for MuPDF. In February 2013, Ghostscript changed its license from GPLv3 to GNU AGPL in version 9.07, which raised license compatibility questions for example by Debian. Aladdin Ghostscript 5.50 and 6.01 AFPL Ghostscript is Aladdin Ghostscript under the AFPL, 6.50 to 8.54, now abandoned. AGPL Ghostscript is the canonical variant available, since February 2013, under the GNU Affero General Public License, a free software license. GNU Ghostscript is now derived from GPL Ghostscript. GPL Ghostscript is the basis for Display Ghostscript, which adds Display PostScript functionality support. Ghostscript is the current commercial proprietary version licensed by Artifex Software for inclusion in closed-source products. Ghost Trap is a variant of GPL Ghostscript secured and sandboxed using Google Chrome's sandbox technology. ESP Ghostscript merged with GPL Ghostscript.

These include: 35 basic PostScript fonts contributed by URW++ Design and Development Incorporated, of Hamburg, Germany in 1996 under the GPL and AFPL, it is a full set fonts similar to the classic Adobe set: Bookman L, Century Schoolbook L, Chancery L, Gothic L, Nimbus Mono L, Nimbus Roman No9 L, Nimbus Sans L, Palladio L, Standard Symbols L, in Type1, TrueType, OpenType formats. The GhostPDL package includes additional fonts under the AFPL, it includes URW++ versions of Garamond, Arial, Antique Olive, Univers, Coronet, Letter Gothic, as well as URW Mauritius and a modified form of Albertus known as A028. Combined with the base set, they represent a little more than half of the standard PostScript 3 font complement.

A miscellaneous set including Cyrillic and fonts derived from the free Hershey fonts, with improvements by Thomas Wolff. The Ghostscript fonts were developed in the PostScript Type 1 format but have been converted into the TrueType format, usable by most current software, are popularly used within the open-source community; the Garamond font has additionally been improved upon. URW's core 35 fonts have been subsequently incorporated into TeX Gyre.
