PDF Signature Tool
Add your signature to a PDF without printing it. Draw your signature or upload an image, drag it into place, add the date or a line of text, and download the signed file. It all happens in your browser.
Drag to move, use the corner squares to resize, and press Delete to remove the selected item.

- Add the date or any text if you need to, then download the signed PDF.
Questions
Is my PDF uploaded anywhere?
No. The PDF is opened and signed inside your browser, so the file never leaves your device.
Is this a legally binding signature?
It places a visible image of your signature on the document. For many everyday documents that is accepted as an electronic signature, but the rules depend on the country and the type of document. For contracts that need an audit trail or a certified digital signature, use a dedicated e-signature service.
Can I sign on my phone?
Yes. You can draw your signature with your finger and drag it into place.
Can I sign several pages?
Yes. Scroll to any page and add a signature, a date or text there. You can add as many as you need.
Does it work with password-protected PDFs?
No. Remove the password in your PDF app first, then sign it here.
