This tool adds a visual signature to your PDF: your name rendered in a handwriting-style font, placed where you want it.
This is valid for most everyday documents:
- Rental agreements and leases
- School forms and permission slips
- Basic contracts and agreements
- Internal approvals and acknowledgments
This is the same type of signature used by DocuSign, HelloSign, and most e-signature tools.
When you might need more: If you're signing high-stakes legal contracts, government documents, or working in regulated industries (banking, healthcare), you may need a cryptographic digital signature. Consult your legal counsel or compliance team for guidance.
