Why convert KEY to PPTX?

.key uses Apple's proprietary ZIP-based format that stores slides as compressed IWA/Protobuf data, which PowerPoint has no reader for. Converting to .pptx lets recipients open and edit the presentation in PowerPoint, Google Slides, or LibreOffice Impress on any platform.

Quality & what to watch

  • Keynote-specific effects such as Magic Move have no .pptx equivalent and will be dropped or replaced with a basic transition.
  • Apple system fonts used in the deck may not be present on Windows, causing text spacing and layout differences in PowerPoint.
  • Keep the original .key file - the .pptx export is a copy, and editing the source then re-exporting avoids round-trip formatting loss.

Frequently asked questions

Can I convert `.key` to `.pptx` on Windows?
Yes - open iCloud.com in any browser, upload the .key file to Keynote for iCloud with a free Apple ID, and download a copy as PowerPoint.
Will animations survive the export to `.pptx`?
Basic transitions may carry over, but Keynote-exclusive effects like Magic Move will be dropped or replaced - review each slide in PowerPoint after converting.
Is `.pptx` the same as `.ppt`?
No - .pptx is the modern XML-based format from PowerPoint 2007; .ppt is the older binary format from PowerPoint 97-2003.
