About JPG to PDF

Almost every official process still wants one PDF, and almost every phone produces separate pictures. So people end up photographing four pages of a tenancy agreement, or both sides of an identity card, and then needing those shots to arrive as a single numbered document. That conversion is the whole job here, and it happens on your own machine. The pictures are read from your device, assembled into a document in the browser tab, and handed back as a download. Photographs of identity papers are exactly the sort of thing that should not be passing through a stranger's conversion queue on the way to becoming a PDF.

What happens to the PDF

Choose your pictures. They can be added in several goes rather than all at once, which is easier when the shots are spread across a camera roll, and the running total is shown as they accumulate.
Put them in order. The list is the document: the first entry becomes page one. Arrows move a picture earlier or later and the remove control drops one that was added by mistake, which beats renaming files so an alphabetical sort happens to come out right.
Decide how each page should be shaped. Matching each image gives a page exactly the size of the picture, with no borders and nothing cropped. Choosing A4 or US Letter places each picture centred on a real sheet with a margin, which is what you want if the result will be printed or if a form insists on a standard page size.
Build and save. Each picture becomes one page, in your order, and the finished document downloads from this tab.

Common jpg to pdf jobs

A multi-page form photographed at a desk

Four photographs become a four-page document in the order you arrange them. Choose A4 if the office receiving it is likely to print it.

Both sides of an identity card

Two shots become a two-page file that satisfies a checklist asking for a single attachment, without either side being sent anywhere to be combined.

Receipts for an expense claim

A month of receipt photographs becomes one document. Matching each image keeps every receipt at its natural shape rather than floating small on a big white sheet.

A file that came out too large

Photographs make heavy PDFs. If the result is over a portal's limit, reduce the pictures before building, or put the finished document through the PDF compressor.

Check before relying on the PDF

Pictures are embedded rather than redrawn, which is the important detail: a JPG carries its existing compression into the document unchanged and a PNG stays lossless. Assembling the PDF does not add a fresh round of quality loss. It also means the document is roughly as large as the pictures were, so eight camera photographs make a large file.
A small picture is never blown up to fill a sheet. Enlarging adds no detail and simply looks soft, so on A4 or Letter a small image is centred at its natural size instead. If you want it to fill the page, enlarge the original first and then build the document.
The result is a picture of a document, not a document. Text inside it cannot be selected, searched, or read by a screen reader, because as far as the file is concerned each page is a photograph. Anywhere that needs searchable text wants a scan with text recognition instead.
Only JPG and PNG can be placed directly. Other formats would have to be re-encoded first, which would cost quality without asking, so they are refused by name instead. Convert an HEIC from an iPhone or a WebP from the web first, then add the result here.

Questions about JPG to PDF

How do I control the page order?

The list order is the page order. Use the arrows beside any entry to move it, and check the numbers on the left before building - they are the page numbers those pictures will occupy.

Does building the PDF reduce quality?

No. Each picture is embedded exactly as it is rather than redrawn, so a JPG keeps its existing compression and a PNG remains lossless. The trade-off is size: the document is roughly as big as the pictures were.

Can I add HEIC photos from an iPhone?

Not directly, because placing them would mean re-encoding and losing quality without asking. Convert them to JPG first, then add the results here. Files are checked by their actual contents rather than their extension, so a renamed file is identified correctly.

Should I pick A4 or match each image?

Match each image when the document will only be viewed on screen: no borders, nothing wasted. Pick A4 or Letter when it will be printed or when a form expects standard pages, and each picture is centred with a margin.
