Frequently asked questions
- Is the PDF uploaded when I sign it?
- No. The signature is embedded locally in your browser.
- Does this count as a legally binding e-signature?
- This tool places a visual signature; it is not the same as a CA digital certificate signature.
- What if my handwriting is shaky?
- Use an image signature or a typed one — on a phone, turn the screen sideways for a steadier signature.
