Add a Signature to a PDF Online

Draw / type / upload a signature, drag it into place - all processed locally

A contract or approval form arrives and needs your signature - printing, signing, and re-scanning is a hassle. This free tool signs the PDF directly: draw with your mouse or touchscreen, type your name in a handwriting style, or upload a photo of your existing signature.

Once created, drag the signature to the exact spot on the page preview and resize it with a slider - what you see is what gets stamped. Sign multiple pages by applying and reopening the tool.

Privacy matters most here: documents that need signatures are almost always sensitive. Everything happens locally in your browser - neither the contract nor your signature image is uploaded anywhere. Note: this adds a visual signature stamp; it is not a certificate-based cryptographic signature.

How to use

Open the PDF to sign (the signing tool appears automatically)
Create your signature: draw it, type your name, or upload an image
Pick the page, drag the signature into position, adjust the size
Click "Download", or "Apply to Document" to keep signing other pages

FAQ

Is this legally binding?

This tool creates a visual signature - the equivalent of printing, signing, and scanning. It carries no digital certificate or cryptographic tamper-proofing. For everyday use (internal approvals, ordinary contracts) it works where both parties accept it; for high-stakes signing use a CA-certificate e-signature service.

What should I draw with?

A mouse works fine on desktop; touchscreens (phone/tablet) feel more natural. Clear and redraw anytime.

What about the background of an uploaded signature photo?

A transparent PNG works best. A photo of your signature on white paper also works - surrounding whitespace is trimmed automatically.

Can I sign several pages?

Yes. Stamp one spot, click "Apply to Document", reopen the tool, switch pages, and repeat - then save once.
