POT to POTX conversion is the process of transforming a PowerPoint template file saved in the binary POT format into the XML-based POTX template format used by modern Microsoft PowerPoint versions. This conversion preserves slide layouts, master slides, and theme information while migrating the file to a more interoperable, open XML structure that improves compatibility and reduces corruption risk.

POT files typically use the MIME type application/vnd.ms-powerpoint, representing binary PowerPoint template files.

POT is an older binary template file format used by legacy PowerPoint versions, while POTX is the modern XML-based template format introduced in PowerPoint 2007 and later. POTX offers improved file stability, smaller size, and better compatibility with current software. Unlike POT, POTX supports enhanced features and easier integration with Office add-ins.
Keep individual POT source files under 50–100 MB for optimal browser-based conversion speed; large embedded videos significantly increase processing time.
To preserve appearance, ensure embedded fonts are available or choose to embed fonts during conversion; otherwise text may reflow on machines without those fonts.
For batch conversions, process files in batches of 10–20 to avoid timeouts; use a desktop tool or API for large-scale automated conversions.
Note format limitation: very old POT files with proprietary macros or uncommon add-ins may lose macro functionality after conversion to POTX (POTX does not store VBA macros by default).
