Microsoft PowerPoint for Windows and Macintosh computers is not free to download as of 2015, but a free trial is available. However, the iOS version of PowerPoint is free for download from the Apple App Store.
Some users may be eligible to download full versions of Microsoft PowerPoint for free if they are students or employees of companies that provide Microsoft Office software to their workers. Another option for those looking for a free presentation program is the OpenOffice Impress program distributed as part of Apache's OpenOffice open-source productivity package. This program is compatible with Microsoft PowerPoint presentation files, though not all features function the same in both programs.
