Page model
Choose standard paper for printing and fit-to-image for edge-matched pages
A4 and Letter create consistent document pages and work well for forms, reports, and printing. Fit to Image uses each source image as the page basis, which preserves varying proportions but can produce mixed page sizes. Set portrait or landscape according to the content, then use margins to prevent important edges from sitting against a printer's non-printable area.
Order and readability
Arrange pages before conversion and inspect small text afterward
Selection order becomes document order unless you rearrange it. Name or organize scans in advance when the sequence matters, and check the PDF from first to last after export. Phone photos with perspective distortion, shadows, blur, or low resolution remain difficult to read inside a PDF; conversion packages the image but does not repair the capture.
Searchability and size
A PDF made from images is not automatically an OCR document
The visible words are pixels, so selecting, copying, searching, and accessibility tools may not recognize them. OCR is a separate process. Large camera photos can also create a heavy PDF; resize or compress delivery copies when appropriate, while preserving clear text and an original set of scans for future processing.
