This article explains what PPTM files are, the different ways you can view or edit them, and how to convert the slideshow to another format, such as PDF or PPTX, or to a video format, such as MP4 or WMV.

A file with the PPTM file extension is a Microsoft PowerPoint Open XML macro-enabled presentation file. They consist of pages/slides that contain text, media files such as images and videos, charts, and other things relevant to a presentation.

Like PowerPoint's PPTX format, PPTM files use ZIP and XML to compress and organize the data into a single file. The difference between the two is that PPTM files can execute macros, while PPTX files, while they can contain them, cannot.

If you just need a super-fast way to view the contents of the file, without any editing or conversion tools and without having to create a user account, you can use GroupDocs.
