Sign PDF Documents Online — Free & Private
Draw a signature with your mouse or finger, or upload a photo of your signature on paper — the light background is stripped automatically so only the ink remains. Pick the page, choose the position, preview it live, and download the signed copy.
Because everything runs in your browser, the document you're signing — contract, lease, consent form — is never uploaded anywhere. For adding text, dates, or initials alongside the signature, use the full PDF Editor, which includes the same signature tool.

FAQ
Is this a legally binding e-signature?
This tool draws a signature image into the document (a "simple electronic signature"). Many everyday agreements accept this, but it is not a cryptographic digital signature with a certificate. For regulated documents, check what the receiving party requires.
Can I sign with a photo of my handwritten signature?
Yes — choose "Upload Image" in the signature dialog. Photograph your signature on plain paper; the background is removed automatically and you can fine-tune the strength.
Can I stop the signature being moved or edited later?
The signature is drawn into the page content, not added as an annotation, so it can't be dragged off in a PDF viewer. For extra protection, encrypt the signed PDF with a password.
