Adobe PDF 8.1

Adobe PDF improves the viewing and manipulation of 3D graphics.

PDF simplifies the navigation of e-mail archives and photo collections.

The standard for more secure, dependable electronic information exchange, PDF is recognized, and often required, by industries and governments around the world. Invented by Adobe in the ‘90s, PDF is and has always been an open specification. This means that other companies may build products and services that create and read PDF files. PDF files and forms also work with assistive technologies to help make information accessible to people with disabilities.
