Important Signature Note

This tool adds a visual signature image to your PDF document. It is useful for signing forms, confirmations, approvals, and everyday documents. It does not create a cryptographic digital certificate signature. For legally regulated digital signatures, you may need a certified e-signature provider depending on your country, organization, or document requirements.
