PPS to PPSX conversion is the process of changing a Microsoft PowerPoint Show file saved in the legacy PPS (binary) format into the newer PPSX (Open XML) format. This conversion preserves slide layout, animations, and multimedia where possible while updating the file to a more compatible, editable, and more secure Open XML package.

Keep individual PPS source files under 250 MB for fastest, error-free uploads; split very large presentations into sections before converting.
To preserve animations, transitions, and timings, convert using a tool that maintains embedded media and avoid pre-saving to PDF; choose the "original quality" media option when available.
For batch conversion, group files with similar media size and settings; convert during off-peak hours if your service throttles large jobs.
