What is PDF?
Adobe® Portable Document Format (PDF) is the #1 standard for sharing electronic
documents on the web. Adobe PDF is a universal file format that preserves all of the fonts, formatting, colors, and graphics of any source
document, regardless of the application and platform used to create it. PDF
files are compact and can be shared, viewed, navigated, and printed exactly as
intended by anyone with a free Adobe Acrobat® Reader.
You can obtain the Adobe Acrobat Reader for free at the Adobe web site.
