How to convert ppsm to pps file

Use .pps when an older presentation system accepts the PowerPoint 97–2003 show format but not .ppsm. The conversion also retains the behavior of opening directly as a slide show.
What PPSM is
.ppsm is the Office Open XML format for a PowerPoint macro-enabled slide show. It contains presentation content and can include VBA macros; opening it normally starts the slide show.
What PPS is
.pps is the older binary PowerPoint Show format used by PowerPoint 97–2003 and supported by later versions for compatibility. It opens directly as a slide show. Unlike macro-free formats such as .pptx, the legacy PowerPoint binary format can contain VBA macros, so changing to .pps does not by itself remove macros or make a file safe to run.

Offline with desktop software
LibreOffice Impress is a free option for Windows, macOS, and Linux. Open the source with File → Open, then choose File → Save As and select PowerPoint 97–2003 AutoPlay (.pps) as the file type. Confirm the output format before saving.
Microsoft PowerPoint for Windows or macOS can open PPSM and save a legacy show. Choose File → Save As, then select PowerPoint 97–2003 Show (*.pps) as the file type.
Compatibility and macro caveats
.pps is a legacy binary format, so newer presentation features, effects, fonts, or media may change during conversion; check the result on the system that will display it. PowerPoint is the better choice if VBA matters, but verify the converted file’s macros. LibreOffice may not preserve or run VBA macros reliably. Do not treat conversion to .pps as a way to remove macros.
