Information on PDF Files

What is a PDF file?

PDF (Portable Document Format) is a file format developed by Adobe Systems as a means of distributing compact, platform-independent documents. PDF documents are superficially similar to HTML.  A PDF document may contain images, text, and hyperlinks. However, as PDF is based on a variant of PostScript, each document is completely self-contained; packing text, graphics, and fonts into a single file. Because PDF documents are World Wide Web accessible, yet display and print exactly as intended, print publishers often favor PDF over HTML.

PDF files can be viewed with the Adobe Acrobat Reader or the Acrobat Reader Web-browser Plug-in, both of which can be downloaded for free from Adobe. PDF files can be created with the full version of Adobe Acrobat.
