Keynote → PNG renders each slide as a sharp image you can drop into a blog post, a report or a design tool, without opening the deck on a Mac.
From real runs
| Element | Result | What happens |
|---|---|---|
| One image per slide | Kept | A five-slide deck gave five PNGs in one ZIP, numbered in slide order; asking for one slide gives a bare PNG. |
| Pixel size | Changed | Slides render at 144 DPI: a 4:3 slide is 2048 × 1536 pixels and a 16:9 slide 3840 × 2160. Set width to 1920 or 1280 for normal screen use. |
| Slide appearance | Changed | The PNG follows our PDF layout, so the backgrounds, colour fills and font changes noted for Keynote → PDF are baked into the picture. |
| Text | Changed | Slide text becomes pixels; it cannot be searched or copied, and screen readers get nothing from it. |
| Presenter notes and builds | Lost | Images show the finished slide only; presenter notes and build steps are not included. |
| Flat colour and line art | Kept | Icon shapes, frames and flat-colour artwork stay crisp edged, which is where PNG beats JPEG. |

The HTTP API and the MCP server run the exact engine this page uses (Office engine → Image engine); the response carries the same warnings the web converter shows. Check support first with GET /api/v1/pairs?from=key&to=png.

A 16:9 Keynote slide is 1920 × 1080 points, and at 144 DPI that becomes 3840 × 2160 pixels. Set width to 1920 or 1280 to get screen-sized images.
No. Each slide becomes one image with everything showing. Keynote's own image export can write each build as a separate file.
No. A single slide comes back as a bare PNG; decks with more than one slide come back as a ZIP in slide order.
