How to Sign a PDF Electronically for Free

The print-sign-scan ritual is one of the most wasteful habits left in office life. You don't need a printer or a scanner to sign a PDF — you can add a signature directly to the file and have it back in someone's inbox in under a minute.

Three ways to create a signature

• Draw it with your mouse, trackpad, or finger on a touchscreen for the most natural look.
• Type your name and let the tool render it in a signature-style font.
• Upload a photo of your handwritten signature on white paper to reuse it anywhere.

Placing the signature accurately

A good signing tool shows the actual PDF so you can drag your signature onto the exact line, resize it to fit, and add the date or your initials nearby. This matters on contracts and forms where the signature box is small — eyeballing the placement on a live preview beats guessing.

Are electronic signatures valid?

In most countries, electronic signatures are legally recognized for the vast majority of everyday agreements under laws like the U.S. ESIGN Act and the EU's eIDAS regulation. A few document types — certain wills, property deeds, and notarized forms — may still require a wet signature, so check the specific requirement if the stakes are high.

Keep the document private

Because you're signing a real document, privacy counts. A browser-based signer keeps the PDF on your device — your signature and the contract are never uploaded — which is the right default for anything legal or financial.
