  3. Tap the page where the signature goes. Drag to move it, and pull the corner to resize.

Tips

Is it legally valid?

A drawn or typed signature is a simple electronic signature, accepted for most everyday documents like rental agreements, offer letters and consent forms. Some legal and government documents need a certified digital signature (DSC) or Aadhaar eSign instead - check what the receiver requires.
