Fill in the rest of the form

Sign PDF: questions and answers
Is this a certificate-based digital signature?
No. This tool places a visible image of your signature on the page. It does not add a cryptographic, certificate-based digital signature, so use a dedicated signing service if your document requires one.
Can I sign a PDF on my phone?
Yes. Open the page in your phone browser, open the PDF and draw your signature with your finger.
Can I use a signature I wrote on paper?
Yes. Take a photo of it or upload an existing picture. You can remove the background so only the ink is placed on the document.
Is my signature sent to a server?
No. The signature is created and placed on the PDF inside your browser.
