Practical guide

When and how to use Sign PDF

Sign PDF places a drawn or typed signature appearance onto a document page. It is useful when a recipient accepts an ordinary visual signature on a form.

A visible signature image is not the same as a certificate-based digital signature, which cryptographically proves signer identity and detects later changes.

Best used for

  • Signing routine consent forms
  • Adding initials or approval marks
  • Completing informal internal documents

Quality checklist

  • Confirm the recipient accepts an electronic image signature
  • Place it without hiding nearby text
  • Review the complete document before sending
