How to sign a PDF online
A contract, a consent form, a rental agreement — most documents that need a signature arrive as a PDF. You do not need to print it, sign with a pen, and scan it back. Here is how to add a real signature on screen in under a minute.
Two ways to sign
There are two honest ways to put a signature on a document without special hardware. You can draw your signature — the closest thing to a pen, and what most people expect on an agreement — or you can type a name in a signature-style font for informal forms. Drawing is the default in Formagator because it produces a mark that looks like yours.

Is an on-screen signature legally valid?
In many jurisdictions a typed or drawn "electronic signature" is legally recognised for everyday agreements, but rules vary by country and by document type, and some formal instruments require a qualified digital signature or a witness. This guide explains the mechanics of adding a signature; it is not legal advice. When a document is high-stakes, confirm the signing requirements that apply to you.
Frequently asked questions
Can I sign on my phone?
Yes, and phones are ideal for drawing a signature with your finger. See filling PDFs on your phone.
Will my signature be editable after I download?
No. The export is flattened, so the signature is part of the page image and cannot be moved by the recipient.
Do you store my signature?
Only if you sign in and choose to save it for reuse. Otherwise it exists only in your browser for that session.
