Convert Keynote to PowerPoint on Windows: KEY to PPTX

You have an Apple Keynote .key presentation, but your next review needs a PowerPoint .pptx copy. Slide text is only part of a presentation: backgrounds, shapes and animation can affect what the audience sees, so check the converted slides before presenting.

View the slides, then save a PowerPoint copy

Key, Pages & Numbers File Opener shows Keynote slides as pages on your Windows PC, without a Mac, Apple ID or upload. Pro saves a PowerPoint copy with the slides and text. It does not include animations in that export.

Open the file with the app

Install Key, Pages & Numbers File Opener from Microsoft Store.
Double-click the .key file or drag it into the window. Drag the whole folder for a file saved as a Mac folder package.
Move through the pages and zoom to check slide text, backgrounds and any display warning.
Choose the PowerPoint saving option (Pro) and save a .pptx copy to your PC.
Inspect the saved slides before presenting, especially background pictures, gradients and shapes. Do not rely on the export to retain animations.

What is free?

Open .key files and view slides page by page.
Zoom, navigate and select or copy text.
Read the file locally, offline, without an Apple ID.

Save and export with Pro

Pro is a one-time purchase with no subscription. Check the Microsoft Store purchase screen for the current price.

Save Keynote as PowerPoint (.pptx). Slides and text carry over.
Save all or selected pages as PDF, save pages as PNG and print.
Convert multiple files to PDF in one batch.

Limits and things that may be missing

Background pictures, gradients and some shapes may be missing from the PowerPoint copy. Animations are not included.
The viewer does not play Keynote animations or transitions, edit .key files or save back to Keynote format.
Password-protected files cannot be opened. Ask the sender for an unprotected copy or PDF.
If conversion fails and the file contains a first-slide preview, the app can show that picture with a notice. It is not the full presentation.

Tested Keynote files range from iWork '09 to 2021. Keep the original and review the .pptx before sharing or presenting it.
