How to sign a PDF

Signing a PDF used to mean printing, signing with a pen, and scanning it back. You don't need any of that. There are three quick ways to add a signature digitally.

1. Draw it

Use your mouse, trackpad, or finger to draw your signature onto a canvas. It captures the natural look of your handwriting and is the closest to a pen-on-paper feel.

2. Type it

Type your name and pick a flowing cursive font. It's fast, tidy, and perfectly acceptable for most everyday agreements.

3. Upload an image

If you have a photo or scan of your signature, drop it in as a transparent PNG and place it where it belongs.

Placing and finishing

Position the signature, resize it, and add the date nearby if needed. When you export, the signature is baked into the page. To stop anyone editing the fields afterward, flatten the document.

Is a drawn signature legally valid?

In most places, a typed or drawn e-signature is legally binding for ordinary agreements, provided intent and consent are clear. For high-stakes documents that need cryptographic proof of identity, that's a different mechanism — see digital signatures vs e-signatures.
