Why convert PRDX to PPTX?

Converting a .prdx to .PPTX lets you open and edit the deck in Microsoft PowerPoint, Google Slides or any modern presentation tool, since .prdx is SoftMaker-only. PPTX is the universal editable presentation standard, making it the natural choice for sharing an editable file.

FreeOffice Presentations FREE

Open the .prdx, choose File | Save as, pick PowerPoint (.pptx) in the file-type list and save. Free on Windows, Mac and Linux.
