- Saving makes the signature part of the page and breaks any existing digital signatures.
Visible signature vs. digital certificate
Sign PDF places your drawn, typed, or uploaded signature onto the page. That’s how most everyday agreements, forms, and approvals get signed. It does not attach a certificate-based digital signature (X.509), a trusted timestamp, or an identity audit trail. If you need those, use a dedicated e-signature service.
Getting it on the line
Use the page selector at the top to jump to the signature page. Add your signature, initials, or date, then drag each one until it sits neatly on its line.
Frequently asked questions
Is this a cryptographic certificate signature or a visible signature?
A visible signature placed on the page. It doesn’t attach an X.509 certificate or verify your identity.
Can I upload a transparent PNG of my handwritten signature?
Yes. Switch to Image, upload a PNG, JPG, or WebP of your signature, and drag it onto the line.
Can I add both my signature and today’s date on the same page?
Yes. Add your signature, initials, and date with the quick-add buttons, then drag each to its line.
