What Is a PPS File?

How to open, edit, & convert PPS files

A file with the PPS file extension is a Microsoft PowerPoint 97-2003 Slide Show file. Newer versions of PowerPoint default to using PPSX instead.

A PPS file can contain different pages called slides that can hold video, audio, text, animations, images, and other items. Apart from one exception, they're identical to PowerPoint's PPT files—the difference is that PPS files open directly to the presentation instead of to the editing mode.

PPS is also an abbreviation for lots of different terms that have nothing to do with the Slide Show file format, like packets per second, precise positioning service, and pre-paid system.

How to Open a PPS File

Most PPS files you'll find were probably created by PowerPoint and can, of course, be opened and edited with it. Another way to view and print (but not change) this kind of file without using PowerPoint is via Microsoft's free PowerPoint Viewer.

Since these files are used by PowerPoint to immediately begin a presentation, opening one by regular means will not let you edit it. To make changes, you need to drag and drop the file onto an empty PowerPoint window or open the program first and then browse for the file from the menu.

A number of free programs also work, including OpenOffice Impress, WPS Office Presentation, and probably other presentation programs and free MS Office alternatives.

If you find that an application on your PC does try to open the file but it's the wrong application or you'd rather have another installed program open it, Windows users can easily change the default program that opens PPS files.

How to Convert a PPS File

The easiest solution is to use PowerPoint. Open the file and then save it to some other format like PPT, PPSX, PPTX, etc. The other editors listed above can convert the file, too.

One example of a compatible online converter is Zamzar. It can save files in this format to PDF, JPG, PNG, RTF, SWF, GIF, DOCX, BMP, and several other formats.

Online-Convert.com is another one that supports saving to video formats like MP4, WMV, MOV, 3GP, and others. PowerPoint can convert PPS to MP4 or WMV as well, through its File > Export > Create a Video menu.

PPS files that have been converted to a video can then be converted to an ISO file or burned directly to a DVD with Freemake Video Converter, and probably some other video converters.

If you want to use the slideshow in Google Slides, you have to first upload the file to your account. Do this by selecting the file picker icon on the right side of that page, and then find the file through the Upload section. Once it exists in your Google account, converting into other formats like PPTX and PDF is possible through File > Download.

In some contexts, PPS stands for packets per second. If you're looking for a PPS to Mbps (or Kbps, Gbps, etc.) converter, see this one at CCIEvault.

Still Can't Open It?

Most PPS files are no doubt used with PowerPoint. If your file doesn't open that way, there's a good chance you're misreading the file extension, confusing another format for this one because the extensions are so similar.

Consider PSS as an example. At a glance, you could confuse it for a PPS file and try to open it with a slideshow program. In reality, it could be a video file used in a PlayStation 2 game, in which case you'd need a video player to watch it.

PSP is another. These are usually PaintShop Pro image files. Again, PowerPoint would most likely display an error if you attempted to use it in this context.
