How to sign a PDF
- 1
Add your PDF
Drop in the document. It opens on your device and is never uploaded.
- 2
Create your signature
Draw it with your mouse or finger, or type your name and use a handwriting style.
- 3
Place and download
Click the page to drop your signature, drag it into position, then download the signed PDF.
Sign documents without handing them to a server
Most online signing tools ask you to upload the contract, NDA or form first — which means a copy of a sensitive document sits on someone else's server. pdfnoupload works differently: your PDF is opened and signed entirely inside your browser with pdf-lib, and the signed file is generated on your own machine. Nothing is transmitted, so there is no copy to leak, log or sell.
Draw, type, place — as many times as you need
Create a signature by drawing freehand or typing your name in a handwriting style, then click anywhere on any page to drop it. Move it, resize it, or add it to several pages — for initials on every page, dates, or a second signer. When you are done, the signature is flattened into the PDF and downloaded instantly. It is free, leaves no watermark, and keeps working offline once the page has loaded.
Frequently asked questions
Is my document uploaded when I sign it?+
No. Everything happens in your browser — you can confirm there are no upload requests in DevTools → Network while you sign.
Is an electronic signature like this legally valid?+
In many countries a typed or drawn signature placed on a document is a valid electronic signature for everyday agreements. For documents that require a certificate-based digital signature, use a dedicated e-signature service; this tool adds a visible signature image.
Can I sign on more than one page?+
Yes. Create your signature once and click each page where you want it — useful for initialling every page or adding multiple signers.
Will the signature stay in place if I open the PDF elsewhere?+
The signature is drawn into the page content, so it stays exactly where you placed it in any standard PDF viewer.
