Hello,
Thanks for your inquiry.Please note that if a signed PDF document is added, it is not allowed to be changed, including merging operations, due to the security mechanism of the signature itself. Once the content of the document changes, the signature will become invalid. You can delete the signature area in the signed PDF document first, and finally adding a new signature again in the merged document.
If you have any other questions, please feel free to write to me.
Sincerely,
Amin
