Frequently asked questions
Is this a legally valid signature?
This adds your drawn signature as an image on the PDF — a simple electronic signature, fine for everyday documents like approvals and consent forms. For contracts with strict requirements, check what your counterparty accepts; certified digital signatures are a separate technology.
Can I sign on my phone?
Yes — the signature pad works with touch, so you can sign with your finger on a phone or tablet.
Are my documents uploaded anywhere?
No. Signing happens entirely in your browser. Your PDF and signature never leave your device.
Can I place the signature on a specific page?
Yes — after uploading, pick any page from the dropdown, plus the corner or center position and the signature size.
What if my PDF is password-protected?
Password-protected PDFs can't be opened by this tool. Remove the password first, then try again.
