Netpbm is an open-source package of graphics programs and a programming library, used mainly in the Unix world. It is included in all major open-source Unix-likeoperating system distributions and also works on other Unix-like operating systems, Windows, Unix operating systems such as Mac OS X, and other platforms.
File formats and programs
Netpbm defines a set of graphics formats called the Netpbm formats:
The more sophisticated PAM (Portable Arbitrary Map) format.
Netpbm contains over 220 separate programs in the package, most of which have "pbm", "pgm", "ppm", "pam", or "pnm" in their names. For example, you might use pamscale to shrink an image by 10%, pamcomp to overlay one image on top of another, pbmtext to create an image of text or reduce the number of colors in an image with pnmquant.
The Netpbm package can, for example, use two successive conversion programs to turn a picture in the PBM format into a .bmp file:

Netpbm format
A Netpbm format is any graphics format used and defined by the Netpbm project. The portable pixmap format, the portable graymap format and the portable bitmap format are image file formats designed to be easily exchanged between platforms. They are also sometimes referred to collectively as the portable anymap format.
