PDF or Image: Which Should You Upload to a Form?

Some forms accept either a PDF or an image. They behave differently for size, multi-page documents, and acceptance. Here's how to choose.

When PDF wins

PDF is better for multi-page documents (everything in one file), for keeping text selectable, and because many official portals specifically expect PDFs.

When an image wins

A single photo or a simple one-page scan can be smaller as a JPG, and some image-only upload fields require it. If the form asks for a 'photo', use an image.

Converting between them

If you have images but need a PDF, combine them into one PDF. If you have a PDF but need an image, export the page as a JPG.
