How to Convert Images to PDF
Turning images into a PDF is one of the most common reasons people show up to a PDF tool — usually to combine a bunch of photos of a document, like a contract shot page by page on a phone, into one shareable file.
Getting the order right
Upload a batch of images and most tools sort them alphabetically by filename, which almost never matches the order you actually photographed them in. Rename with a number prefix first (01, 02, 03...) or use a tool that lets you drag to reorder before generating the file.
Matching page size to content
Photos of documents usually look best on a standard page size like A4 or Letter, so the result prints and displays the way people expect. Photos meant to be viewed as images — a portfolio, say — often look better matching the photo's own aspect ratio instead.
Better photos, better results
Shoot in good, even light, and hold the camera as directly overhead as you can — angled shots distort text and make it harder to read. Auto-crop or auto-straighten features can patch minor issues, but a clean photo to start with saves you a step later.
One image per page, or a grid
Most tools default to one image per page. Want two smaller images — receipts, say — sharing a page? Check whether your tool has a grid layout option, since not all of them do.
