A form asks for “one PDF”, and what you have is five phone photos. Emailing five JPGs looks messy, half the upload forms reject multiple files, and the printed pile arrives out of order. Combining the photos into a single PDF fixes all of it — and takes about a minute in the browser, with nothing installed and nothing uploaded.
The one-minute version
- Open the Image to PDF converter — phone or computer, any browser.
- Drop or select the photos. Each becomes one page; arrange the order with the ↑↓ arrows.
- Pick a page size — A4 with a margin for document-style, “Fit to each image” for artwork — and click Create PDF.
JPGs go in untouched — zero quality loss — and iPhone HEIC photos are handled automatically.
Settings that make it look right
- Photographed documents (contracts, forms, receipts): A4 portrait, 10 mm margin. Crop each photo to the paper edges first — the crop tool takes seconds per photo — and the result reads like a real scan.
- Artwork, screenshots, certificates: “Fit to each image”, so every page is exactly the image with no borders.
- Mixed portrait and landscape photos: A4 keeps every page the same orientation with the photo centred; fit-to-image lets each page follow its photo.
Hitting an upload size limit
Five 8 MB photos make a 40 MB PDF — over most portals' limits. Two fixes, in order of quality kept: shrink the photos first with the image compressor (quality 80 is visually identical and about a quarter of the size), then build the PDF; or build first and run the result through Compress PDF, whose Balanced preset is made exactly for photographed documents. Aim under 10 MB for email, under 5 MB for most portals.
Getting pages back out
Made the PDF and later need one photo back, or the pages as images again? PDF to JPG renders any page at screen or print resolution, and Split PDF pulls out pages as a smaller PDF.
