Put photos into one PDF
Drop the pictures in the order you want the pages. JPG and PNG are embedded directly. WebP is drawn onto a white page first, then saved as JPEG inside the PDF. Phone photos work, including HEIC after you convert them with HEIC to JPG.
To go the other way, use PDF to JPG. To shrink the PDF afterward, use compress PDF.
