QUICK ANSWER
Is it possible to convert PRSX to PPSX?
Yes - PRSX converts to PPSX.

Both .prsx (SoftMaker) and .ppsx (PowerPoint) are auto-playing slide-show files, so this is a direct like-for-like save. Open the .prsx in SoftMaker Presentations, choose File > Save as, and pick PowerPoint Show (.ppsx) from the file-type list. The resulting file plays full-screen and opens in PowerPoint.

Why convert PRSX to PPSX?

Recipients who use Microsoft PowerPoint cannot open a proprietary .prsx, so converting to .ppsx gives them a native show that runs immediately. Both formats are the show variant of an ordinary presentation, so the mapping is natural. It is the right choice when you want the file to launch straight into the slideshow.

How to convert PRSX to PPSX

SoftMaker Presentations EASIEST

Open the .prsx, choose File > Save as, open the Save as type dropdown and select the PowerPoint Show (.ppsx) format.

FreeOffice Presentations FREE

The free FreeOffice edition opens .prsx and saves to PowerPoint formats; save as .pptx then rename to .ppsx, or pick the show format if offered.

Microsoft PowerPoint APP

First save the .prsx as .pptx in Presentations, open that in PowerPoint, then use File > Save As > PowerPoint Show (*.ppsx) for a fully native show.

Quality & what to watch

  • SoftMaker's PowerPoint export is very compatible but not perfect - complex animations, effects, or unusual fonts can shift slightly.
  • .ppsx only changes how the file opens (it auto-plays); the slide content is the same as the equivalent .pptx.
  • Round-tripping through PowerPoint gives the cleanest .ppsx if fidelity matters for a specific deck.
