PPS

Microsoft PowerPoint Slide Show

The PPS (PowerPoint Slide Show) file format is a Microsoft PowerPoint file type designed specifically for presenting slideshows without requiring editing capabilities. It can be opened and viewed using Microsoft PowerPoint, PowerPoint Viewer, or other compatible presentation software, but editing requires converting it to the PPT or PPTX format. PPS files contain pre-rendered slides with animations, transitions, and multimedia elements, ensuring smooth playback during presentations without exposing the underlying design or content structure.

PPSX

PowerPoint Open XML Slide Show

PPSX is a file format used for PowerPoint slide shows, based on the Open XML standard, allowing for the presentation of slides in a read-only mode. It can be opened and viewed using Microsoft PowerPoint, PowerPoint Viewer, and other compatible presentation software, ensuring accessibility across platforms. The format stores slides, media, and animations in a compressed, XML-based structure, supporting advanced features like embedded multimedia, transitions, and interactive elements while maintaining a smaller file size compared to traditional PPT formats.
