Convert PRSX to PRDX

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

.prsx and .prdx are the same SoftMaker Presentations format in two flavors: .prsx auto-plays as a slide show, while .prdx is the normal editable document. Open the .prsx, choose File > Save as, and select Presentations document (.prdx). No data changes - only the open behavior does.

Why convert PRSX to PRDX?

People convert a locked-down show back to a .prdx so it opens as an ordinary editable document instead of launching full-screen every time. Both are native SoftMaker formats, so the conversion is loss-free and instant. It is the right move when you need to keep working on a deck that was saved as a finished show.

How to convert PRSX to PRDX

FreeOffice Presentations FREE

The free FreeOffice edition opens .prsx and saves to .prdx the same way, since both are its own native formats.

Rename via a copy FREE

Because the formats are internally the same, opening the show in Presentations and re-saving as .prdx is the safe way; do not just swap the extension on the raw file.

About these formats

Quality & what to watch

  • The conversion is loss-free because .prsx and .prdx share the same underlying SoftMaker format.
  • The only real change is behavior: .prdx opens as an editable document, while .prsx auto-plays when double-clicked.
  • Use File > Save as inside Presentations rather than blindly renaming the extension, so the header is written correctly.
