You’ve Finished Your Deck. Now What?
This isn’t a trivial question. Different situations demand different formats:
- Sending to your boss for review → PDF (they only need to view, not edit)
- Sending to a Windows colleague who needs to edit → PPTX
- Sharing in a WeChat group or Slack → Video or GIF
- Embedding on a website → HTML or image sequence
- Presenting live yourself → Just play it natively in Keynote
Pick the wrong format and you’ll feel it immediately: the PDF you sent to a colleague who needs to make edits. The PPTX that opens with mangled layouts on Windows. The native Keynote file that the recipient can’t even open.
Let’s fix that.
Format 1: PDF — The Safe Bet
Best for: Sending to executives or clients, printing, archiving, anyone who doesn’t need to edit.
What’s good about it:
- Opens on literally any device — Windows, Android, iOS, Linux
- Layout is pixel-perfect, guaranteed — what you see is what they get
- Relatively small file sizes
- You can password-protect it
How to export: File → Export To → PDF → Choose quality (“Good” is fine for screen viewing; “Best” for print)
What you lose:
- Animations — all static
- Editable content — it’s locked
- Embedded video becomes a static frame
Best practice: Treat PDF as your “deliverable” format. Build in Keynote → export PDF for review → if they need changes, send an editable format as round two. PDF first keeps things clean.
I’ve seen too many people send editable files to executives who then spend 20 minutes accidentally moving a logo. Send PDF. Protect them from themselves.
Format 2: PPTX — The Compatibility Compromise
Best for: Windows colleagues who need to edit the file in PowerPoint.
How to export: File → Export To → PowerPoint → Click “Next” to save.
The hard truth: Keynote-to-PPTX is a lossy conversion. These things will break or degrade:
- Magic Move transitions → become generic fade transitions
- Keynote-exclusive fonts → revert to system defaults (often Arial or Times New Roman on Windows)
- Complex build orders → may shuffle or break
- Instant Alpha-processed images → backgrounds may reappear
- Shape merge results → may rasterize into flat images
How to minimize the damage:
- Do a test export and open it in PowerPoint before sending
- Stick to universal fonts (Arial + a system sans-serif)
- Avoid Keynote-exclusive features if you know the file will go to PowerPoint
- When in doubt, send PDF for viewing and PPTX only when editing is truly needed
PowerPoint compatibility has improved, but it’s not seamless. The gap is smaller than it was five years ago, but it’s still there.
Format 3: QuickTime Video — The Social Media King
Best for: Sharing in chat apps, uploading to video platforms, embedding in web pages.
How to export: File → Export To → QuickTime → Choose resolution (1080p is plenty) → Set slide duration.
Recommended settings:
- Resolution: 1080p (1920×1080) — sufficient for almost everything
- Slide duration: 3–5 seconds for auto-play; longer if you’ve recorded narration
- Format: H.264 — the most universally supported codec
The killer advantage: Video preserves every animation and transition intact. That elaborate Magic Move sequence you spent an hour tweaking? It plays perfectly in the exported video. Every build, every bounce, every dissolve — rendered frame by frame.
Watch out: Before exporting, change your animation triggers to “After Previous” and set a specific timing. Otherwise your video will have animations that never fire because there’s no click to trigger them.
Format 4: GIF — Social Media’s Secret Weapon
Best for: Twitter/X posts, product feature snippets, tutorial demonstrations, quick before/after comparisons.
GIF limitations you need to know:
- 256 colors only — gradients and photos will look posterized and ugly
- File sizes get huge fast (a 10-second 1080p GIF can hit 50MB)
- No audio
- Loops forever, but you can’t control playback speed
What actually works well as GIF:
- Solid-color backgrounds with simple animated shapes
- Quick product feature walkthroughs (2-3 steps)
- Before/after data comparisons (two images alternating)
- Logo animations
What doesn’t: photos, gradient backgrounds, complex charts with subtle color variations, anything with more than 10 seconds of motion.
One trick I use: design your slide with a flat background specifically so it GIFs well. If you know something is destined for Twitter, design it for 256 colors from the start.
Format 5: Image Sequences — Turn Slides Into Web Assets
How to export: File → Export To → Images → Choose one PNG or JPEG per slide.
Best for:
- Uploading to a CMS where each slide becomes a separate image block
- Building long-scroll landing pages by stitching slides together
- Social media carousel posts (LinkedIn, Instagram multi-image)
- Creating a PDF alternative when you need individual image files
This format is underrated. If you’re building a product page and want to show a feature walkthrough, exporting slides as images gives you perfect, consistent visuals without needing a designer to recreate everything in Figma.
Format Selection Cheat Sheet
| Situation | Recommended | Backup |
|---|---|---|
| Executive review | — | |
| Windows colleague editing | PPTX | PDF preview + PPTX |
| Sharing in chat apps | QuickTime video | GIF |
| Live meeting presentation | Keynote native | PDF backup |
| Printing | — | |
| Website embed | Video or image sequence | PDF download link |
| Social media post | GIF | JPEG image |
What About File Size?
Export format choice heavily affects file size, and that matters when you’re emailing or messaging files:
- PDF: a 30-slide deck with images typically runs 2–8MB at “Good” quality. Very manageable.
- PPTX: similar to PDF — 3–10MB for a typical deck. The conversion sometimes bloats files slightly if Keynote rasterizes complex elements.
- QuickTime video at 1080p: roughly 50MB per minute of content. A 5-minute deck becomes a 250MB file — too large for most email attachments, but fine for cloud sharing links.
- GIF: wildly unpredictable. A 5-second simple animation might be 2MB. A 10-second complex one could hit 30MB. Always check the file size before sending a GIF.
- Image sequence (PNG): about 200–500KB per slide at 1080p resolution. A 30-slide deck becomes roughly 10–15MB total.
If file size is a concern, PDF at “Good” quality is almost always your best compromise between visual fidelity and transferability. When in doubt, export a test, check the size, adjust quality settings, and export again. The 30 seconds of testing saves the frustration of a bounced email.
A Quick Note on Accessibility
PDFs exported from Keynote generally preserve text as selectable/copyable content, which means screen readers can parse them. PPTX exports also maintain text accessibility. Video and GIF formats, however, lose all text accessibility — if your audience includes people who rely on screen readers, always provide a PDF version alongside any video export.
The Takeaway
Export decisions take 30 seconds. Getting them wrong costs your recipient 5 minutes of frustration and you a round of back-and-forth messages.
The rule is simple: they need to view → PDF. They need to edit → PPTX. They need to see the show → Video. And never send a native .key file to someone who doesn’t use a Mac.
