PPSX and PPTX are both modern PowerPoint Open XML formats with identical internal structure — the only difference is the file extension. PPSX auto-launches as a slideshow when opened, while PPTX opens in editing mode. The slide content, themes, animations, media, and all other data are stored identically in both formats.

PPSX files are designed for viewing, not editing. When you receive a PPSX slideshow and need to modify content, update slides, or extract elements, you need the PPTX version that opens in editing mode. This conversion is the standard way to unlock editing on slideshow-only presentations.

PPTX is also the default format for PowerPoint workflows. Cloud platforms (OneDrive, Google Slides), collaboration tools, and version control systems all handle PPTX as the primary editable format.

LibreOffice opens the PPSX and saves as PPTX. Since both formats use identical OOXML structure (ZIP-compressed XML), the conversion is effectively a re-save with the PPTX extension. All slide content, themes, master slides, animations, transitions, embedded media, speaker notes, and metadata are preserved exactly. The XML content within the ZIP container is identical.

No. PPSX and PPTX are the same format. All content is preserved identically.

While renaming often works, proper conversion ensures format validation and file integrity.

Yes. All animations, transitions, and timing are preserved identically.

No. PPTX opens in editing mode. Save as PPSX again if you need slideshow behavior.

Yes. All notes, comments, and metadata are preserved exactly.
