Digital signatures removed when inserting file into another PDF

[Guy_I]

I regularly assemble large documents -- 2,000-plus pages -- that consist of multiple chapters & appendices converted to PDF from Word files. The final insertion into the large document is a digitally signed letter from the person approving the overall document. When I insert the letter into the large PDF, Acrobat strips out the digital signature. Is there any way around this, other than printing the signed letter and scanning it into a PDF?

It isn't exactly stripped out. What you want to do is beyond impossible. Digital signatures apply to an entire PDF - never to single pages. So you can't add or subtract pages in a signed document or combine it, the signature us either lost or utterly broken and useless. This is why PDF portfolios were invented.

I was afraid it couldn't be done. I'll ahe to investigate portfolios, then. Thanks.

solved with https://pdfjoiner.com/ it showed the signature properly. maybe it can work for your needs as well

I have to do this on a routine basis and have found a work around.  Open the pdf containing the digital signatures.  Print to pdf.  You can now add this new pdf file to another pdf and it will retain the digital signatures.  Hope that helps.

I to have to Print to save the signature when I need to save a signed document to another PDF "packet". Has there been a fix through Adobe?  If not when will this issue be addressed???

NO--this will completely remove the digital signature.  All it will keep is the picture/image of the signature, which means nothing as it is then no longer verifiable.

they will have to verify last pdf created anyway
