How to fill and sign a PDF on iPhone

Rental applications, school forms, contracts: fill in every blank and add your signature on your iPhone, in a couple of minutes, without printing anything or uploading the form.

Step by step

  1. Open Sheaf, tap Import a file (or share the form to Sheaf from Mail or Files), then choose Fill & Sign.
  2. The blanks on the page light up. Tap the first one, or tap Start.
  3. Type your answer. Tap Next ▸ to jump to the next blank, so you never have to hunt for the next line.
  4. Date blanks open a date picker, so dates come out in a clean format.
  5. When you reach the signature line, draw your signature with your finger. It lands right on the line, sized to fit.
  6. Tap Save, then Save to Files or Share to send it back.
The form never leaves your iPhone. Sheaf reads and fills it on your device, which matters for forms full of personal details.
