Tips for better results

  • Drawing with a finger on a phone gives a more natural signature than a mouse on a laptop.
  • Place the signature so it touches the signature line without covering the printed name underneath.
  • This produces a visible, drawn signature — the kind most agreements and internal approvals ask for. It is not a certificate-based digital signature.

Examples

Open the PDF, draw your signature on a phone, drag it onto the line, add the date if the form asks for it, and download the signed file to attach to your reply.
