How to sign a PDF online for free (without printing)
Add your signature to a PDF in the browser — no printer, no scanner, and nothing uploaded to a server.
The old way to sign a document was to print it, sign with a pen, scan it back in, and email it. You can skip all of that — draw your signature once and drop it straight onto the PDF.
Open the PDF
Drop your document into the Sign PDF tool; it renders page by page.
Draw your signature
Sign in the pad with your mouse, trackpad or finger. Clear and redo until it looks right.
Place and size it
Click on the page where the signature should go and adjust the size, then export the signed PDF.
Is a drawn signature legally valid?
For most everyday agreements — forms, letters, internal approvals — a drawn signature placed on the document is widely accepted. For contracts that require a certified, audit-trailed e-signature, use a dedicated e-signature service. This tool is about convenience, not legal certification.
Why do it in the browser?
Signing a document often means the document is sensitive. Because everything here happens on your own device — the PDF and your signature never touch a server — there's no copy of your signed document sitting in someone else's cloud.
Need to fill in text fields too, or add a date? Combine it with the Add Page Numbers and Watermark PDF tools.
