This file format was created by Adobe Systems in 1993. It is heavily used in business. People like it because it prints so nicely. What comes out of the printer is exactly what went in. No funny formatting. No strange migration of page elements.
On a computer, it does need special software to be read. That's no big deal. Adobe offers its Reader free of charge. Currently, that is version 9. Download it here .
You have a choice of ways to create a PDF file. If you have Microsoft Word 2007, use that. I assume you want to send the message in the e-mail. Highlight the message and press Ctrl+C. Open a blank Word document. Press Ctrl+V to paste the e-mail into Word.
Click the Save icon in the top left of Word. The Save As window will open. At the bottom of the window, name the file. In the Save As Type box, click the down arrow. Select PDF. Click Save.
You may not have Word 2007. No problemo. There are other ways to skin this cat. (I am a dog person. However, I would never, ever skin a cat! My dogs would, though.)
I have two conversion programs on my site. They are doPDF and PDFCreator . Both are free.
Once installed, these programs show up in your printer list. When you're ready to convert a document, print as you normally would. But instead of the printer, use the PDF listing. There's really nothing to it!
