Choose ODP Slide Size, Aspect Ratio and Page Fit

The source page and destination slide often have different proportions. A portrait report placed on a widescreen slide needs a deliberate fitting rule or the result will be cropped, distorted or surrounded by unexpected space.

01

Choose a slide canvas for the audience

A single ODP normally uses one page layout for the complete deck. Source ratio therefore follows the first selected PDF page and should be reviewed when the source mixes page sizes.

Understand contain, cover and stretch

Contain keeps the entire page visible and may leave background margins. Cover fills the canvas by cropping equal areas from opposite edges. Stretch fills the canvas without cropping but changes proportions.

Contain is the safest default for reports, forms and evidence. Cover suits photographic pages when edge loss is acceptable. Stretch should be used only when distortion is intentional.

03

Preview representative pages before processing

Review a dense page, a page with edge content, and any page with a different orientation. The live preview shows the chosen canvas and fit behavior before upload.

Background color matters only where contain leaves margins. Use white for paper-like reports or a deliberate brand-neutral tone for display decks.
