NetPBM is a package of over 220 programs that convert from one graphics format to another and do simple editing and analysis of images. There are no interactive tools in this package, and nothing that displays graphics of any kind. It is like a non-GUI equivalent of ImageMagick, GIMP, and Adobe Photoshop, etc.

Netpbm is an open source package of graphics programs and a programming library, used mainly in the Unix world. It is a highly portable package, working under many Unix platforms, Windows, Mac OS X, VMS, Amiga OS and others and is included in all major open source Unix-like operating system distributions. As of February 24, 2006, the latest beta version is 10.31 (released December 23, 2005), and the latest stable version is 10.26.25 (released February 19, 2006).
