If you use Keynote on your Mac, you have probably noticed that Gamma only exports PowerPoint (.pptx) and PDF — there is no native .key export. When you open that PPTX in Keynote, the "Made with Gamma" badge comes along for the ride, sitting on the slide master where you cannot click it in the normal editing view.
This guide covers two clean paths: removing the badge before it ever reaches Keynote, and removing it inside Keynote itself.
Why the badge survives the Keynote import
Keynote faithfully imports the PPTX slide masters and layouts. The Gamma badge is a shape hyperlinked to gamma.app on one or more of those masters, so it appears on every slide that inherits from them — exactly the same behavior as in PowerPoint. Keynote's normal editing view does not expose master elements for selection, which is why clicking the badge does nothing.
Best path: clean the PPTX first, then open in Keynote
This avoids fighting Keynote's master-editing quirks entirely:
- In Gamma, export your deck as PowerPoint (.pptx) (Share, then Export, then Export to PowerPoint).
- Open the PPTX watermark remover in your browser.
- Drop in the .pptx file — the gamma-linked badge shape is removed from every master and layout in seconds. The file never leaves your browser.
- Open the cleaned .pptx in Keynote. The badge is already gone; fonts, animations, and layout import as usual.
This is the fastest route and the only one that is truly lossless — no manual editing, no risk of missing a layout.
Alternative: remove it inside Keynote via Edit Slide Layouts
If you already have the deck open in Keynote and want to fix it in place:
- Click View in the menu bar and choose Edit Slide Layouts (or right-click any slide thumbnail and choose Edit Slide Layout).
- In the layout editor, look for the "Made with Gamma" badge — it is usually in the bottom-right corner of the master or one of the layouts.
- Click the badge and press Delete.
- Check every layout in the sidebar — the badge can appear on more than one. Delete each copy.
- Click Done to exit the layout editor.
- Scroll through your slides to confirm the badge is gone, then save.
Where the Keynote method gets tricky
- Multiple layouts. Gamma decks often use several layouts, and the badge can sit on each one. Miss a layout and some slides keep the watermark.
- Keynote's PPTX rendering is imperfect. Complex Gamma themes with custom fonts, layered gradients, or advanced animations may look different after import regardless of the watermark — cleaning the PPTX before import does not fix Keynote's conversion limitations.
- No Keynote on iPhone/iPad layout editor. The mobile version of Keynote does not expose slide layout editing, so you need a Mac for the manual method. The browser-based remover works on any device.
What about .key files from other tools?
Some open-source tools (like the DedInc GitHub project) advertise Keynote .key support via AppleScript round-tripping: convert .key to PPTX, clean, convert back. This requires Keynote to be installed and running, works only on macOS, and the double conversion can degrade fidelity. If your starting point is a Gamma export (which is always PPTX or PDF), there is no reason to go through .key at all — clean the PPTX directly."
Keynote vs. browser removal
| Edit Slide Layouts in Keynote | Clean PPTX first, then import | |
|---|---|---|
| Needs a Mac | Yes | No — any browser, any device |
| Catches all layouts automatically | Only if you check each one | Yes |
| Risk of Keynote conversion artifacts | Already imported | Same (Keynote converts either way) |
| Time | 2-5 minutes | Seconds |
Frequently asked questions
Can I export directly from Gamma to Keynote format? No. Gamma exports PPTX and PDF only. To get a Keynote file, export as PPTX, clean the watermark, then open in Keynote and save as .key.
Will cleaning the PPTX break anything when I open it in Keynote? No. The remover only deletes the gamma-linked badge shape from the slide masters. Every other element — text, images, charts, animations — stays byte-for-byte identical, so Keynote imports the same content minus the badge.
I only have the PDF export. Can I still use Keynote? Clean the PDF with the PDF watermark remover first. You can then insert the cleaned PDF pages into Keynote as images, though you lose editability. For an editable deck, re-export from Gamma as PPTX instead.
