How to turn JPG images into a PDF
Choose the photos or scans and put them in order, then pick the page size. Each image gets its own page: on A4 or Letter it is centered and scaled to fit inside the margin without cropping, and Same as each image makes each page the size of its picture.
JPG photos go into the PDF as they are, without being compressed again, so they keep their quality; a photo the camera stored sideways is turned upright first. PNG keeps its transparent parts, which show as white paper.
Worked example
Three phone photos on A4 with a small margin make a 3-page PDF, one photo per page, each scaled to fit inside 190 × 277 mm.
Before you rely on the result
JPG, PNG, WebP and GIF images (a GIF gives its first frame), up to 100 images and 400 MB in all. An iPhone HEIC photo opens only in a browser that can show it, such as Safari; elsewhere, save it as JPG first. Nothing is uploaded.
