PDF files. Portable Document Format. The pop up everywhere, and seem to have become a standard in computer documents.
What PDF Files Are
PDF files came into being in 1993 as the brainchild of Adobe. They provide a way to view documents and graphics without having the same software that was used to create the document.
How Do You Make PDF?
It used to be that you could only make PDF files by using the expensive Adobe Writer software. However, PDF creation software is now openly available for free. Using one of these packages, which shows up as another printer in your list, you print to the PDF software. The results are a PDF file.
Why Use PDFs?
The main reason to use PDF documents is to create a document that can be viewed by a large number of people, regardless of how the document was originally created. In these days of Web applications, PDF documents also allow documents to be served off the Web with their original formatting intact, while remaining searchable.
