Signing PDF document failed

I couldn’t sign my PDF document. What can I do?

There might be a few reasons for this:

  • PDF is password protected 

Skribble doesn’t support signing password-protected PDF documents. To sign the document, you’ll have to remove the password. 

  • PDF is too large
The size of your PDF document cannot exceed 40 MB. To check the size, right-click on the document and go to Properties. We recommend keeping the PDF size under 40 MB.
  • PDF is broken

    Your PDF document seems to be broken or doesn't comply with the common PDF standards. There are different online tools available that make it easy to check whether your document meets these standards or not.

    If any of these issues persist and you’re not able to sign, please contact our support team at
