One file instead of many attachments
Sending ten separate photos is awkward for everyone. Some upload forms accept only one file, email clients pile attachments into a confusing list, and the recipient has to open each picture to know what it is. Combining the images into a single PDF solves all three: one upload, one attachment, and a document that reads in order from the first page to the last.
Typical cases: the front and back of an ID plus a proof of address for an application; every page of a signed contract photographed on a phone; a set of receipts for an expense report; homework pages a teacher wants as one file; product photos for a quote.
Getting the order right
Order matters when someone has to review pages. After selecting the images, drag the thumbnails until they're in the sequence you want. The PDF follows the order on screen exactly. If you select files in a different order than you meant, just rearrange them here instead of starting again.
Forgot an image? Download the PDF, then use “Merge PDF” to add another document, or “Organize PDF” to move, rotate or delete pages and insert a blank page.
Mixed sizes and shapes
When images have different sizes, such as a wide screenshot, a portrait photo and a square graphic, the page settings keep the PDF consistent. Choose A4 or Letter to give every page the same paper size, with each image fitted inside, and leave orientation on automatic so wide images get landscape pages. Choose “Same as image” if you prefer each page to match its picture exactly.
A small margin gives a printed document a tidy, uniform look.
Size of the combined PDF
A PDF made from many photos can be heavy. If it's above a form's limit, send it directly to “Compress PDF” and type the target size; scanned and photo PDFs are exactly what that tool shrinks best. JPGs that don't need rotating are embedded without recompression, so the PDF won't lose quality on the way.
If the people receiving it will print the document, choose the paper size they use and keep a small margin, so nothing falls into the printer's unprintable edge.
