How to Sign a PDF on iPhone Without Printing It

Printing a form, signing it with a pen, and scanning it back in used to be normal. It doesn’t have to be anymore — your iPhone or iPad can sign a PDF directly, and the result looks just as official.

What you actually need

To sign a PDF digitally, you need three things:

1. A way to open the PDF on your device
2. A way to draw or place your signature onto the page
3. A way to save and share the signed version

Step by step

1. Open the PDF from Files, Mail, or wherever it’s stored.
2. Switch to the Sign tool. You can draw your signature with your finger or Apple Pencil, type it in a handwriting-style font, or reuse a signature you’ve saved before.
3. Place it on the page. Drag it to the signature line and resize if needed.
4. Save. The signature becomes part of the PDF itself — not a separate image layered on top that could shift or get lost.

Saved signatures save real time

If you sign documents more than once a month, saving your signature is worth it. Instead of redrawing it every time, you drop in the same clean signature in one tap. PDF Go keeps your saved signatures, typed text options, and stamps all in the same Fill & Sign tool, so contracts, forms, and waivers all go through the same quick flow.

Beyond just signing

The same toolset that handles signatures also covers:

• Typed text — for filling in names, dates, and short answers directly on the page
• Stamps — for “Approved,” “Paid,” or custom stamps you create once and reuse
• Image placement — for dropping in a logo or scanned initial

None of it requires printing anything. Once you’re done, you can share the signed PDF straight from your phone by email, message, or AirDrop.
