Keynote is Apple's presentation program, and its .key files don't open in PowerPoint on
Windows. Converting gives you a PPTX to edit and present in PowerPoint, or a PDF to show on any
screen.
How to convert Keynote to PowerPoint
- Add the
.keyfile above (or several, or a ZIP of folders). - Keep Convert to: Word, Excel or PowerPoint: presentations become PPTX. Choose PDF to present or share without editing.
- Press Convert and download the result.
Presentations from Keynote '09 and from recent Keynote versions (tested with files from 2018 and 2026, including files saved as a package, a folder that looks like a single file on a Mac) are read. Files from some other versions open with empty slides; the report says so.
What comes across
- Every slide in order, with its titles, text boxes, bullet lists and tables.
- The slide size (standard 4:3 or wide 16:9).
What to check
- Themes and pictures: backgrounds, photos and theme graphics are read from the file where the Keynote format allows it, but some come out plain; compare with the PDF.
- Layout: rotated text boxes come out straight, and pictures cut to a shape show whole; compare with the PDF.
- Animations and transitions (Magic Move, builds) don't come across.
- Fonts: Mac fonts (Gill Sans, Avenir, Marker Felt…) are replaced, which can change how titles wrap. The report lists every font and what it became.
- Password-protected presentations can't be opened here.
A Mac with Keynote can export to PowerPoint itself (File > Export To > PowerPoint); this converter is for when there's no Mac at hand. Keynote for iCloud does the same in a web browser on Windows: upload the file at icloud.com, open it and choose Download a Copy, then PowerPoint.
