A recipient using PowerPoint 97–2003 or a legacy presentation system may require a .pps file instead of .ppsx. Converting provides the older show format, but features unsupported by that format may change or be lost.
What PPSX is
.ppsx is the Office Open XML PowerPoint Show format. PowerPoint and compatible presentation apps use it for presentations that open as slide shows in supported software.
What PPS is
.pps is the binary PowerPoint Show format used by PowerPoint 97–2003. It is suited to workflows that require that legacy format. Its presentation data uses the same binary format as legacy .ppt; in PowerPoint, the .pps extension signals that the file should open as a slide show.
How to convert a PPSX file to PPS
Online on 101convert.com
- Upload the
.ppsxfile to the converter on 101convert.com. You can add several files for batch conversion; the page shows the per-file size limit. - Run the conversion and download the resulting
.ppsfile. The conversion runs on the site’s server with LibreOffice.
Uploading sends the presentation to the service, so use this method only for files you are permitted to share.
Offline with desktop software
LibreOffice Impress is free and runs on Windows, macOS, and Linux. Open the file with File → Open, then use File → Save As and select PowerPoint 97–2003 as the file type. Impress may save it with a .ppt extension. If it does, rename the saved file’s extension to .pps; enable file extensions in your file manager first to avoid accidentally creating a name such as presentation.pps.ppt.
Microsoft PowerPoint for Windows can save directly in the legacy show format. Open the file, choose File → Save As, and select PowerPoint 97–2003 Show (*.pps). The option’s wording may vary by version.
Compatibility and quality
.pps supports fewer features than .ppsx, so newer effects or content may be altered or omitted. Check animations, transitions, fonts, and embedded media after conversion. PowerPoint generally opens both show formats as slide shows; other presentation apps may open them for editing or render some effects differently.
