How can I make Acrobat PDFs from PowerPoint?
You can always make PDFs in the usual way, by printing to the printer driver installed by Adobe Acrobat or one of the other commonly available PDF drivers/utilities as described in Make PDFs from PowerPoint
If you have PowerPoint 2007, there's a free add-in from Microsoft that lets you export PDF directly from PowerPoint. 2007 Microsoft Office Add-in: Microsoft Save as PDF or XPS
If you have Mac PowerPoint X, you can save directly to a PDF using OS X's built-in PDF feature.
See How to create PDFs from Mac PowerPoint to learn how.
Or you can use the PDFMaker add-in that Adobe adds to PowerPoint when you install Acrobat ($$$).
Either way, you should get good quality PDFs, but they'll be missing some or all of the interactive features you added to your original PowerPoint presentation. None of these methods fully supports links, action buttons, sounds or movies, even though support for all these features is available in Acrobat.
Our Prep4PDF PowerPoint add-in lets you preserve most of the interactivity in your PowerPoint presentations when you convert to PDF. You can learn more at our Prep4PDF site.
