OS X has the Adobe PDF format as an underlying system. That means that any application can produce a PDF file.
To make a PDF file it is sufficient to "print" it. Follow these steps:
- open the document for which you want to make a PDF file (we will use Excel as an example):
- choose Print... from the File menu:
- click "Save as PDF" and save the file (using extension .pdf if necessary).
- use the resulting file in e-mail or to place on the web.
The result, as presented in Acrobat Reader:

Using PDF ensures:
- that you can make the document available to users of all platforms
- that is can be printed in high quality (because it's vector graphics)
- that the user does not need the application to see the result.
