How to Open a Keynote (.key) File on Windows
A .key file in your inbox and a presentation to give on a Windows machine: PowerPoint will not touch it. Here is what actually works.
Fastest: convert it online
Upload the .key file to the converter on this site and download a PowerPoint (.pptx) with each slide’s text, plus a PDF of every slide exactly as designed. Free, no Apple ID required.
Presenting rather than editing?
Use the PDF download — it preserves every slide pixel-perfect, fonts and all, and presents full-screen from any PDF viewer. For a talk you are giving as-is, the PDF is often the safest option on unfamiliar hardware.
iCloud.com (needs an Apple account)
Keynote for iCloud opens .key files in a browser and exports to PowerPoint. Fine if you have an Apple ID; the export handles most slides but animations and some fonts change in translation.
