What is PDF? How do you use PDF files?

PDF stands for Portable Document Format.

Developed by Adobe, PDF files are viewable and usable across many different platforms.
You can read and print a Macintosh generated document from your Windows-based machine.

Font and graphic information is embedded in the PDF file.
PDF files are based on PostScript, so they print well on almost all printers.

PDF is the format used by the Federal Government for online versions of the Federal Register and online copies of tax forms.

Adobe has a free PDF reader called Adobe Acrobat Reader which will allow you to use PDF files.
You can download Adobe Acrobat Reader at:
