"PDF" stands for Portable Document Format.
PDF is a fast, easy and reliable way to share documents. Any printable document can be converted to PDF, then the PDF file can be linked to from a Web page, attached to an email, or recorded onto a disk or CD for distribution.
A well made PDF file will look the same on all computers, regardless of operating system, system fonts, or Web browser. The layout, typefaces, links, pagination, and images will remain consistent with the original document.
