Why convert KEY to KEYNOTE?
Apple changed the default extension from .keynote to .key starting with Keynote '09; both use the same ZIP-based binary package format with IWA/Protobuf slide data. Renaming the file changes nothing internally. No format difference exists to bridge, so no converter is needed or possible.

- Renaming
.keyto.keynote(or vice versa) changes only the filename; the internal structure is identical and any current Keynote version opens both. - If you need to share the presentation with people who do not have Keynote, export to PPTX (opens in PowerPoint and Google Slides) or PDF via Keynote for iCloud at icloud.com/keynote.
- Older
.keynotefiles saved before Keynote '09 used a macOS bundle format rather than a ZIP package; modern Keynote still opens these without a conversion step.
Frequently asked questions
I found a `.keynote` file online - do I need to convert it to open it?
.keynote and .key files directly.My converter does not list `.keynote` as an output - what should I pick?
.pptx or .pdf. There is no practical reason to target .keynote since .key and .keynote are the same format.
