Drop your photos or scans, download one PDF. Each image becomes a page, and pages follow the order the files arrive in.
Pages are sized to your images. No A4 squeeze, no margins, no white borders: a 3000×2000 photo becomes a 3000×2000 page, edge to edge. Print menus already know how to fit a page onto paper, and nothing is gained by squeezing it into A4 here first.
Sideways phone photos come out upright. Phones often save a photo sideways with a note telling viewers to rotate it. PDF readers ignore that note, which is why converted photos so often lie on their side. This tool reads the note and straightens the page before it goes in.
Your image bytes are kept. Unless a photo needed straightening, each JPG is embedded byte for byte: no re-encode, no quality loss, and the PDF weighs about what the images weigh. PNGs keep their transparency.
One image or fifty. A single image makes a single-page PDF. Fifty stack into fifty pages, in order; want a different order, number the filenames (01, 02, 03) and select them together.
The document is assembled on your device and never uploaded. An ID, a contract or a medical letter stays where it already is. HEIC photos from an iPhone take one stop at the HEIC converter first.
