PPS is a legacy PowerPoint Slide Show file (binary BIFF format, PowerPoint 97-2003) that auto-plays as a slideshow when opened. PPTX is the modern PowerPoint format (OOXML, introduced with Office 2007) that opens in editing mode and supports advanced features like SmartArt, improved charts, better media embedding, and smaller file sizes through ZIP compression.

Legacy PPS files are limited by the PowerPoint 97-2003 feature set — maximum 2GB file size, limited chart types, no SmartArt, and no modern media embedding. Converting to PPTX modernizes the file while also making it editable (PPS opens as slideshow, PPTX opens in edit mode).

PPTX is the current standard for presentation files. Cloud platforms (OneDrive, Google Slides, SharePoint), modern collaboration tools, and current PowerPoint versions all handle PPTX as their primary format. Converting legacy PPS archives ensures continued compatibility with current tools.

LibreOffice opens the PPS binary file and exports as PPTX OOXML. The conversion transforms binary BIFF slide records into XML-based Open XML markup within a ZIP container. Slide content, text, shapes, images, charts, and formatting are mapped from binary structures to their XML equivalents. Master slides and layouts are converted to PPTX slide masters. Animations and transitions are mapped to their OOXML equivalents. File size typically decreases due to ZIP compression.

No. PPTX opens in editing mode. To get auto-play behavior in the modern format, save as PPSX.

Most animations convert to their PPTX equivalents. Complex or custom animations should be verified.

PPTX files are typically smaller due to ZIP compression of the XML content.

Yes. PPTX opens in editing mode with full access to modify content, add slides, and use modern features.

You can save PPTX as PPS in PowerPoint, but it's better to keep the PPTX as your working copy.
