PDF file uses

Adobe Portable Document Format (PDF) is the open, de-facto standard for electronic document distribution worldwide. 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.

With pdfFactory, you can create PDF files from any application quickly and easily.  Once created, the PDF can be shared with other users on the web, emailed, or used for archival purposes.  Adobe Acrobat Reader is required to view and print PDF files.
