Why convert PNG files to PDF locally
Many portals refuse a zip of pictures and ask for one PDF. PNG to PDF Converter at https://png2pdfs.com/ handles that in the tab: choose images, drag to set order, pick page size and margins, then download. Conversion is free, needs no signup, and keeps files on your phone or computer.
Transparent PNG logos are matted to white before they enter the PDF so printouts stay readable. Fit-image, A4, and Letter layouts are available. The merge page on the same site is for stacks that are already split; the homepage is for a normal conversion pass.
