When JPG to PDF earns its place

A contractor photographing receipts for a client expense pack. A site contractor photographed a stack of material receipts with a phone camera at the end of each week, then combined the JPGs into one PDF per job. The accountant received a single paginated file that matched the line items on the invoice, instead of twenty loose images scattered across email threads. Zooming into each receipt in the PDF still showed the printed prices clearly, because the original JPEG data was embedded rather than re-compressed.

A student turning ID photos into a single application packet. A graduate applicant needed passport-style JPG photos of their diploma, transcript and a signed declaration attached as one file to an online portal. They placed the three images on A4 pages in the order the form requested and uploaded a single PDF. The admissions office accepted it on the first attempt, and the student did not have to fight a portal that rejected multi-file uploads.

An author digitising handwritten manuscript pages. An author photographed fifty handwritten notebook pages that predated any digital draft and combined them into one PDF. Each page was sized to match the photo, so nothing was cropped and nothing sat behind white bars. Sharing the file with an editor was as simple as sending a link; the editor could search, annotate and print the pages without juggling a folder of camera-roll images.
