Standard pages preserve the image aspect ratio, center it in the available area and scale it down or up uniformly. Auto orientation follows the rotated image shape. Fit pages instead use 0.75 PDF points per source pixel, corresponding to 96 pixels per inch mapped to 72 points per inch.
Standard paper uses points
A4 is 595.28 × 841.89 points in portrait; US Letter is 612 × 792 points. Margins remove 0, 18 or 36 points from every edge before the uniform fit is calculated.

Open the downloaded PDF, count its pages, scan the first and last page, and confirm rotation, margins, sharpness and order. Keep the source images because a successful browser export does not certify suitability for a particular destination.
