Frequently Asked Questions

Is this a cryptographically valid signature?

No — this places a visual signature image, like signing paper. For cryptographically verifiable signatures, use the Sign PDF tool with a certificate.

Does my signature image stay on PrivaTools?

No. It's used only to render the output PDF and is deleted immediately afterwards.

Can I use a signature image I already have?

Yes — upload a transparent PNG of your signature instead of drawing one.
