Portable Document Format
PDF is a file format created by Adobe Systems to make possible the easy exchange of electronic documents. On the web, its chief advantage is its print-readiness.
To read a PDF file, if a PDF reader is not installed on your computer, you must download and install one.
- Acrobat Reader is the most common choice provided free from the creators of PDF.
- Foxit Reader is "small, fast, clean" and free for all those who want a minimal PDF reader.
