Frequently asked questions
Is this a legally binding signature?
It adds a visible signature image to the document, which is what most everyday forms need. It is not a cryptographic digital signature (PKI); for that, use a certificate-based service.
Can I sign on more than one page?
You can place a signature on the page you're viewing. Move between pages with the Prev/Next buttons and place it where it's needed before downloading.
Is my document uploaded?
No. The PDF and your signature never leave your device — signing happens entirely in your browser.
