Logo by David Ross Design

What is the GD library? GD is an open source code library for the dynamic creation of images by programmers. GD is written in C, and "wrappers" are available for Perl, PHP and other languages. GD creates PNG, JPEG and GIF images, among other formats. GD is commonly used to generate charts, graphics, thumbnails, and most anything else, on the fly. While not restricted to use on the web, the most common applications of GD involve website development.

You probably do not need to download gd

If you are anything other than C programmer gd is probably included with your system or available with a single package manager command. If you're compiling stuff, you're doin' it wrong. See the gd FAQ for more information and please stop compiling things from source code if you don't need to.

GD has moved

The GD library has moved to libgd.org.
