Sign PDF on iPhone: what you need to know

When someone emails you a form to sign, you can do it straight from your iPhone. Open the PDF from Mail or Files, draw your signature with your finger, place it on the page and download the signed copy — all in Safari.

It also works on iPad (great with Apple Pencil) and on Android phones. Nothing is uploaded, so it's safe for contracts and personal documents.
