Pptx Export

Pre-Export Checklist

Before exporting, verify:

1. Frontmatter has marp: true
2. All image URLs are accessible (absolute URLs or local paths)
3. Custom CSS is applied via style directive in frontmatter
4. Slide count and content are finalized

Known Limitations

• Standard PPTX: Slides are PNG screenshots — text is not editable
• Editable PPTX: Experimental feature, visual fidelity may differ from HTML preview
• Editable PPTX: Requires LibreOffice Impress on the server
• Custom fonts may not render correctly in PPTX
• Animated elements are not supported in PPTX output

Fallback Strategy

If LibreOffice is unavailable, fall back to standard (image-based) PPTX. Inform the user that the exported file will have high visual fidelity but text will not be editable in PowerPoint.
