JPG to PDF

Photographing a document and sending the picture is fine until whoever receives it needs a single file, in order, that prints properly. That is really what this tool is for: turning a handful of photos — a signed form, a set of receipts, pages of a passport — into one PDF that behaves like a document rather than a folder of images.

Each image becomes one page. You choose the paper size, and by default the page orientation follows each picture, so a landscape photo gets a landscape page instead of sitting as a thin strip across the middle of a portrait one. Images are scaled to fit inside the page and centred, never cropped: a tool that silently cut the edges off a scanned form would be worse than no tool at all.

There is also a fit-to-image option, which makes every page exactly the size of its picture. That is the right choice for something that will be read on screen rather than printed, because it leaves no white border at all.

WebP, HEIC and other formats are converted on the way in, since PDF itself can only carry a small set of image encodings. JPG and PNG files are embedded exactly as they are, so a photo's original quality survives untouched rather than being re-compressed for no reason.

All of it runs on your device. The images are read, arranged and written into a PDF by your own browser, so nothing is uploaded — which is the point, given that the things people most often convert this way are identity documents and financial paperwork.
