POTM to OTB conversion is the process of transforming a Microsoft PowerPoint Macro-Enabled Template (.potm) into an OpenDocument Template-Based Presentation (.otb), preserving slide layouts, themes, and embedded macros where possible. This conversion enables templates created in PowerPoint to be used in applications that support the OTB presentation template format, facilitating cross-software template reuse and distribution.

POTM files are Microsoft PowerPoint template files that store themes and layouts, while OTB files are OpenDocument Presentation Template files used primarily in open-source suites. While POTM focuses on Microsoft ecosystems, OTB offers broader compatibility with open-source presentation software. Converting POTM to OTB allows users to utilize templates across diverse platforms efficiently.
Keep individual POTM files under 50–200 MB for faster, more reliable conversions; very large files may require desktop tools.
To preserve visual fidelity, embed fonts in the POTM before converting and choose 'retain original media' or high image quality in output settings.
For batch conversions, group templates with similar themes and disable unnecessary embedded media to reduce processing time and avoid timeouts.
Note format-specific limitation: OTB (OpenDocument template) may not support all PowerPoint-specific animations, transition effects, or proprietary SmartArt; test critical slides after conversion.
