How to Sign a PDF Electronically for Free

You don't need to print, sign, and rescan a document to add your signature. You can sign a PDF electronically in your browser in seconds — and it looks far cleaner than a scan.

Three ways to sign

1. Draw it. Use your mouse, trackpad, or finger (on a touchscreen) to draw your signature, just like signing on a delivery pad.
2. Upload an image. Already have a photo or PNG of your signature? Drop it in.
3. Type it. Type your name in a handwriting-style font for a quick, legible mark.

How to sign a PDF step by step

1. Open your document in the PDF editor.
2. Choose the Sign tool and draw your signature in the pop-up pad.
3. Click Place signature, then drag it where it belongs and resize with the corner handle.
4. Add the date next to it with the Date tool if the form needs it.
5. Download the signed PDF.

Are electronic signatures legal?

In most countries, electronic signatures are legally valid for the majority of everyday agreements — think rental applications, consent forms, and business contracts. Laws such as the U.S. ESIGN Act and the EU's eIDAS give electronic signatures legal standing. For high-stakes documents (wills, certain notarized forms), check whether a qualified or notarized signature is required.

Keep your signature private

Your signature is sensitive. Avoid tools that upload your document and signature image to a server. Our editor keeps everything on your device, so your signature is never stored anywhere you don't control.

Make it look professional

• Sign on a clean background and crop tightly if you upload an image (a transparent PNG works best).
• Keep the signature proportional — don't stretch it.
• Place a typed name or title underneath if the form expects it.
