Ghostscript
Novato, California, USA
What it is
Ghostscript is a free PostScript and PDF interpreter and rendering engine from Artifex Software Inc. It renders and converts PDF, PostScript, PCL, and XPS files, including conversion to PDF/A. For PDF workflows, it offers compression with adjustable settings, optimization, rasterization, vector output, and an OCR device that can make printed or scanned material searchable. It can run as a command-line application or be integrated into another product as an SDK; its gsapi interface has bindings for Python, C#, and Java. Other capabilities include color management, overprint simulation, N-up imposition, screening, and trapping. The maker lists document conversion, archiving, previews, e-invoicing, pre-press, printing, and document management as uses. Ghostscript runs on Windows, macOS, Linux and other Unix-like systems, VMS, and embedded systems, as well as host-based, SaaS, and cloud environments. The AGPL release is free, but commercial licensing applies to certain closed-source distribution and SaaS deployments under Artifex’s guidance. Conversion may not preserve extra metadata such as embedded files or document outlines.
