About the Sign PDF
The Sign PDF tool lets you add your signature to contracts, agreements, forms, invoices and letters without printing and scanning. Create your signature by drawing it with your mouse, finger or stylus, typing your name in a handwriting style, or uploading a photo of your signature.
Click anywhere on the document to place the signature, drag it into position and resize it with the handle. You can also add the date, your name or initials with the Text tool. The signed PDF is created entirely in your browser, so your signature and documents are never sent to a server.
Note: this tool adds a visual electronic signature. Some legal processes require a certified digital signature with a certificate; check the requirements for your document.
Making a signature that looks right
Three ways to create it
- Draw: works best with a finger on a phone or a stylus on a tablet. On a laptop, draw slowly with the mouse and redo it until you are happy.
- Type: enter your name and pick a style. It looks neat and is quick, which suits internal forms and approvals.
- Upload: sign on white paper with a dark pen, take a photo in good light, and upload it. For the cleanest result, remove the paper background first with the Background Remover.
Placing it on the page
- Zoom the preview so you can line the signature up with the signature line.
- Use Add text next to it for the date and your printed name, if the document asks for them.
- Choose blue ink if the other party needs to tell the signed copy from a photocopy.
Whether a simple electronic signature is accepted depends on the document and the country. Most everyday agreements accept it, while some official documents require a certified digital signature.
