Quick Verdict
Use PPTX when…
Use PPTX for any presentation that will be shared in business environments, opened in Google Slides, or presented on a computer you don't control — PPTX has universal support and is the expected format.
Use ODP when…
Use ODP if you work primarily in LibreOffice Impress and want an open-standard format with no vendor tie-in. ODP is fine for internal use, but convert to PPTX or PDF before sharing with PowerPoint users.

Frequently asked questions
How much is lost converting PPTX to ODP?
Basic presentations (text, images, simple transitions) convert well. Complex presentations lose significant fidelity: custom animations may break or disappear, SmartArt becomes static shapes, embedded videos may not transfer, and exact spacing can shift. Always review a converted presentation before using it.
Can I present an ODP file in PowerPoint?
PowerPoint can open ODP files (File → Open), but compatibility depends on the features used. Basic slides usually render correctly. Check all animations, transitions, and media before presenting — and always test on the presentation computer beforehand. A safer approach is to export from LibreOffice Impress as PPTX or PDF before sharing.
Is it better to export presentations as PDF?
For presentations where you only need to show (not edit) the slides, PDF is often the safest format: fonts are embedded, layout is fixed, and it opens everywhere. The downside is that PDF loses animations and transitions — slides appear static. LibreOffice Impress: File → Export as PDF. PowerPoint: File → Export → Create PDF/XPS.
