Free PDF Signer - Add Your Signature to PDF Online
Draw, type, or upload your signature and place it on any PDF page. Your signed PDF downloads instantly. 100% browser-based — no uploads, no accounts.
What is Sign PDF?
Signing PDF documents no longer requires printing, signing by hand, and scanning back to digital. Our free PDF Signer lets you add your signature to any PDF page directly in your browser — draw it with your mouse or touch, type it in a handwriting-style font, or upload an existing signature image.
Place the signature anywhere on any page by dragging it to the perfect spot. Resize it as needed. When you're happy with the placement, the signature is embedded into the PDF's content layer using pdf-lib, producing a standard PDF with your signature permanently integrated.
This is the fastest way to sign a lease agreement, approval form, offer letter, NDA, or any other document that requires your authorisation. No DocuSign subscription needed. No printing. No scanning.
Because the signing happens entirely in your browser, confidential documents — NDAs, employment contracts, financial agreements — are never transmitted to any server. The final signed PDF is generated locally and downloaded straight to your device.
