What this tool does
Sign PDF adds your handwritten signature to a PDF. You make the signature once, on screen, then place it exactly where the document asks for it, on one page or on every page.
Features
- Three ways to sign: draw with a mouse, finger or stylus; type your name in a handwriting style; or upload a photo of your signature on paper.
- Clean photo signatures: the white paper is removed, so only your ink shows on the page.
- Black or blue ink, and an optional date line under the signature.
- Place it by clicking or dragging on a preview of the page, or move it with the arrow keys.
- Any page, or every page, for documents that ask for initials on each page.
- Rotated pages are handled, so the signature is always upright as you read the page.
Limits
- The signature is an image on the page, not a certificate-based digital signature.
- Asking other people to sign (sending a document out for signatures) isn't available.
- Password-protected PDFs need to be unlocked first.
- Typed signatures use handwriting fonts installed on your device, so the look varies between devices.
Where your file is processed
This tool works in your browser: your PDF is processed on your own device, so it isn't sent to our server for this tool. Some other tools on UtiloNest do use our server, and their pages say so.
Frequently asked questions
Is a signature added this way legally valid?
In many countries a simple electronic signature like this is accepted for everyday agreements, such as forms, letters and many contracts. Some documents, such as certain property, court or notarised papers, need a certified digital signature or a signature in ink. If you aren't sure, ask the person or organisation that sent you the document.
Is this the same as a digital signature with a certificate?
No. This tool places a picture of your signature on the page, which is what most people mean by signing a PDF. It doesn't add a cryptographic certificate, so it doesn't prove that the file wasn't changed later.
How do I make a photo of my signature look clean?
Sign in dark ink on plain white paper, and take the photo in good light without shadows. Keep "Remove the paper background" ticked, so the paper becomes transparent and only your strokes are placed on the page.
Can I add the date next to my signature?
Yes. Tick "Add today's date" and the date is written under your signature, in the same ink colour.
