You add your signature, hit Save, send the file—and the recipient says: “Messaged, but I see no signature.” Confusing and embarrassing.

User reported issues

A Reddit thread shows:

“The recipient sees a blank PDF. I used Acrobat, they opened it in macOS Preview.”    


That illustrates: you sign, but depending on the software, the electronic signature disappears.

What’s the cause

  • Some PDF viewers strip out embedded digital signature layers.
  • The signature was added “on top,” not baked into the file.
  • Emailing through Outlook or Preview may remove it in Outlook’s inline view.

Patchy fixes

  • Flatten the PDF using SmallPDF or PDF24.
  • Take a screenshot of the signed doc and recreate it.
  • Use “Print to PDF” to embed the signature.
  • All hacks—slow, messy, and frustrating.

Why it matters

You feel double-pain: “Did I sign it?” followed by the recipient asking “Where’s the signature?” That undermines trust and slows business.
