Frequently asked questions
Does Keynote export to PPTX cleanly?
For simple presentations (text, images, basic transitions), Keynote's PPTX export is good. Keynote-specific animations (Magic Move, 3D transitions) are replaced with PowerPoint equivalents. Complex builds with multiple text animations may require manual review after export.
Can I open a KEY file in PowerPoint?
Not directly. PowerPoint cannot open .key files natively. Export from Keynote to PPTX first, or use iCloud Keynote online to convert. There's no direct KEY→PPTX conversion in third-party tools.
