Keynote to PPTX when you are the one receiving the deck

Apple introduced Keynote in January 2003, and it ships free on every Mac, iPad and iPhone. Its files open in nothing else: PowerPoint, Google Slides and LibreOffice Impress cannot read a .key file, while Keynote itself happily opens PPTX. So the conversion burden lands on whoever does not own Apple hardware.

Typical cases: a speaker emails a .key the night before an event, an agency sends a pitch deck to a client's Office-based marketing team, a student hands in a Keynote project to a teacher on a Windows PC. Asking the sender to re-export works if you can reach them in time. Otherwise, converting the file yourself gets you an editable PowerPoint deck in a minute. For the technical background on what a .key package contains, see KEY to PPTX.

Keynote files that arrive as a folder or a ZIP

A Keynote document can be saved either as a single file or as a package, which is really a folder that macOS displays as one icon. When a package is emailed or copied to Windows, it shows up as an ordinary folder or gets wrapped into a .zip, and no converter can read it as a deck. Ask the sender to choose File > Advanced > Change File Type > Single File in Keynote on the Mac and send it again; the resulting single .key file uploads normally here.

Presenting the converted deck on a Windows PC

Open every slide once; Apple fonts such as Helvetica Neue are replaced by fonts Windows has
Play each video, and convert QuickTime clips to MP4 if one stays black
Check the slide size under Design > Slide Size; Keynote's wide 1920 × 1080 deck matches PowerPoint's 16:9
Start Presenter View and confirm your notes are under the right slides
Replay builds and transitions; effects without a PowerPoint equivalent become plain cuts
Copy a PDF of the deck to the same USB stick as a fallback

Keynote and PowerPoint format facts

KEY

Apple Keynote presentation

KEY is the file format of Apple Keynote, the presentation app Apple introduced in 2003. It supports polished themes, cinematic transitions, Magic Move animations and embedded media. Only Apple devices open .key files natively; PowerPoint, Google Slides and Windows need a converted copy. Keynote can export to PPTX, PDF and video, though some effects may be simplified.

PPTX

Microsoft PowerPoint presentation

PPTX is Microsoft PowerPoint's default presentation format since Office 2007, based on the Office Open XML standard. It stores slides, layouts, images, charts, speaker notes, transitions and embedded media in a ZIP package of XML. It is the most widely used format for slide decks in business and education. Google Slides, Keynote and LibreOffice Impress open PPTX, though fonts, animations and layout may change slightly.

PPTX converter

A Keynote file reaches people who have no Apple software: a client on Windows, an event technician loading the podium PC or a teacher whose school runs Office, and PPTX is the one presentation format all of them can open and edit.

Keynote to PPTX: what presenters ask

Can the sender export to PowerPoint from Keynote on an iPad or iPhone?

Yes. Keynote on iPad and iPhone has an export option in its share and export menu with PowerPoint as a choice, and Keynote for iCloud in a browser can download a copy as PowerPoint. Converting here is the alternative when the sender is unavailable or you have a stack of .key files and no Apple device.

Will Google Slides open the converted deck?

Yes. Google Slides cannot import .key files, but it imports PPTX through File > Open > Upload. Once in Slides, the deck can be shared and edited by everyone with a link, which is often the easiest way for a mixed Mac and Windows team to collaborate.

Will my presenter notes appear in PowerPoint's Presenter View?

Speaker notes written in Keynote are carried into the notes pane of each PPTX slide, so they show in Presenter View on the presenter's screen while the audience sees only the slides. Check long notes for line breaks after converting.

Why does a video on one slide not play on the Windows laptop?

Keynote often stores clips as QuickTime .mov, sometimes encoded in HEVC, which a Windows PC may lack a decoder for. Microsoft recommends MP4 video with H.264 and AAC audio for PowerPoint. Convert the clip to MP4, as described in how to convert MOV to MP4, and insert it again.

Is a PPTX or a PDF better for a podium PC I have never seen?

PPTX if you need to edit, use Presenter View or run animations. A PDF is the safer fallback because it looks the same on any machine; Keynote to PDF makes one. Carrying both on a USB stick costs nothing.
