Prepare Keynote slide backgrounds for 16:9 or 4:3 displays, then choose Scale to Fill or Scale to Fit inside the presentation.
Choose the Keynote format you need, then review its source notes, crop, and image quality.
Match a full-slide image to the deck's aspect ratio before adding it as a background. Compare the documented and working canvases for other presentation apps.
Put one image on each page, arrange the order, and create the PDF in your browser.
Confirm the slide size in the Document sidebar before resizing. Apple lets you enter a custom size when a preset does not match the target screen.
Scale to Fill covers the slide but may crop the image; Scale to Fit preserves the full photo but can leave space. Preview the composition for both.
