About POT to PPTX Conversion
POT (PowerPoint Template) is the legacy binary template format from PowerPoint 97-2003. PPTX (PowerPoint Open XML Presentation) is the modern XML-based format introduced with PowerPoint 2007. Converting POT to PPTX modernizes the template content from a proprietary binary structure to the open XML standard, enabling full compatibility with current PowerPoint versions, Google Slides, Keynote, and web-based presentation tools.
The conversion transforms the OLE2 compound document structure into a ZIP package containing XML files for slides, themes, and relationships. This makes the content accessible to a vastly wider range of applications while preserving the visual design of the original template.
Why Convert POT to PPTX?
Modern PowerPoint versions display a Compatibility Mode warning when opening legacy POT files, and some features are restricted. Converting to PPTX provides full access to current PowerPoint features including modern transitions, morph animations, 3D models, and real-time collaboration. The PPTX format is also the standard for PowerPoint Online, SharePoint, and Teams integration.
PPTX files are smaller than their binary equivalents due to ZIP compression of the XML content. The open XML structure also makes PPTX files more resilient to corruption — individual XML components can be inspected and repaired, unlike monolithic binary POT files where a single corrupted byte can render the entire file unreadable.
Common Use Cases
- Upgrading legacy POT templates to modern PPTX for current PowerPoint versions
- Enabling cloud collaboration on template content via PowerPoint Online and SharePoint
- Converting POT templates for import into Google Slides and Keynote
- Modernizing corporate template libraries from binary to Open XML format
- Creating editable PPTX presentations from legacy template designs
How It Works
LibreOffice parses the POT binary OLE2 stream, extracting slide master records, layout definitions, theme colors, font tables, embedded images, and shape properties. These elements are reconstructed as PPTX Open XML components: slide layouts map to ppt/slideLayouts/*.xml, theme colors become ppt/theme/theme1.xml, embedded media goes into ppt/media/, and relationships are defined in .rels files. The entire package is ZIP-compressed into the final PPTX file. The OOXML structure follows ECMA-376 specifications.
Quality & Performance
Most template elements convert well including slide layouts, color themes, backgrounds, and font specifications. Some legacy binary-specific features — OLE embedded objects, VBA macros, and certain animation types — may not transfer to PPTX. Complex gradient fills and shadow effects may render with minor visual differences. Overall, the conversion produces a fully functional modern presentation from the legacy template.

Tips for Best Results
- 1After conversion, save the PPTX as POTX in PowerPoint to create a proper modern template file
- 2Review each slide layout in the PPTX to verify placeholder positions and formatting transferred correctly
- 3Update legacy fonts to modern equivalents (e.g., replace Arial with Aptos, the new PowerPoint default) during the migration
- 4Test the converted presentation in PowerPoint Online to verify cloud compatibility
- 5Archive the original POT alongside the PPTX during the transition period for reference
POT to PPTX is the essential modernization step for legacy PowerPoint templates. The conversion enables full modern feature support, cloud collaboration, and cross-platform compatibility.
