Converting between presentation documents is a common task, especially when dealing with different versions of Microsoft PowerPoint. PPS is used to display presentations directly as finalized documents. PPT is an older format compatible with PowerPoint 97-2003. PPTX, the default editable format in the latest version of PowerPoint, offers better data recovery capabilities, smaller file sizes, and enhanced security.

Whether you need to edit PPS documents or ensure compatibility with modern tools and features, converting them to PPTX is essential. This article will demonstrate how to convert PPS and PPT to PPTX documents using Python with Spire.Presentation for Python. Read on to learn more.
