What is a POTX file?

PowerPoint Open XML Template

Developed By
Microsoft
Initial Release
2007
MIME Type
application/vnd.openxmlformats-officedocument.presentationml.template

The POTX file is the standard XML-based template format for Microsoft PowerPoint 2007 and later, standardized under ECMA-376 and ISO/IEC 29500. It uses ZIP compression to package XML data structures describing slide layouts, themes, and master slides. Unlike POTM, the POTX architecture strictly prohibits the inclusion of VBA macros, making it a safer alternative for distributing design standards without security risks.

How to open a POTX file

POTX files are the default template standard for modern presentation software. Microsoft PowerPoint provides full native support. Alternatively, users on non-Windows platforms can utilize Apple Keynote (macOS), Google Slides (web-based), or LibreOffice Impress, all of which accurately interpret the OOXML schema for editing and playback.
