Combine Images Into One PDF

Plenty of submission forms accept exactly one file and expect it to be a PDF: expense claims with a dozen receipts, a tenancy application with proof of income, a customs declaration with the front and back of an ID. What you have is a folder of photos. This page takes those images and builds a single PDF with one picture per page, in the order you add them, each placed on an A4 page and scaled to fit so the document prints and reads normally.

JPG and PNG are both accepted and can be mixed in the same file, and there is no page count to worry about. The PDF is assembled on your device; the images are never uploaded, which is the right way to treat the kind of paperwork people merge: identity documents, signed pages, medical letters, bank statements. There is no watermark stamped on the pages.

Two practical notes. The PDF is only as light as the images that go into it, so ten 5 MB phone photos make a heavy document that may bounce from an email; compress the photos first with the Compress Image tool on this site if size matters. And a phone photo of a page goes in tilted and shadowed; passing the pages through the Document Scanner first produces a PDF that looks like a real scan.
