PPSX Slideshow Format
PPSX (PowerPoint Open XML Slideshow) is the modern equivalent of PPS using the Office Open XML format. Opening a PPSX file launches a full-screen slideshow directly. It is a ZIP archive with the same structure as PPTX but with a different relationship type specifying slideshow mode.

PPSX — PowerPoint Open XML Slideshow Format
PPSX is the Open XML equivalent of the legacy PPS slideshow format, introduced with Office 2007. Like PPS, a PPSX file opens directly in full-screen slideshow mode when double-clicked. Unlike PPS, PPSX uses the modern ZIP-based OOXML package structure, sharing its internal layout with PPTX.
PPSX vs PPTX
PPSX and PPTX are structurally identical except for the presentation relationship type declared in the package. PPTX specifies an editable presentation, while PPSX specifies a slideshow. This means conversion between the two is straightforward with no data loss.
Converting PPSX Files with LetsConvert

Unlocking a PPSX for Editing
Convert PPSX to PPTX to get a fully editable version of the presentation. All slides, layouts, themes, and embedded assets are preserved. The resulting PPTX file opens in edit mode in any compatible presentation application.
Why Convert from PPSX?
PPSX files are optimised for viewing but not editing. Converting to an editable format enables collaboration, branding updates, or content reuse.
