Converting from PPS
PPS (PowerPoint Show, 97-2003) is a binary Microsoft PowerPoint file that opens directly in full-screen slideshow mode rather than in the editable presentation editor. PPS files are functionally identical to PPT files but are launched differently by the operating system. They are commonly used for distributing self-running presentations and kiosk displays.
Why Convert PPS Files?
Converting PPS to PPTX or ODP allows the presentation to be edited in modern tools. Converting to PDF creates a static document suitable for sharing as a report or handout. Many recipients cannot open PPS files directly without Microsoft PowerPoint, making conversion to more accessible formats practical for wider distribution.
