Hi team - apologies, but my google-fu is failing me - only getting spammy sites with no real value results.
I need to shrink PDFs (over 10k of them, in PDF/A format) but keep the e-signature completely intact. Using a CLI tool on Linux but it scrapes off the certificate during the removing PDF/A, shrinking, and re-PDF/A-ing.
Can anyone advise a dummy like me? Thanks!
Do you by "e-signature" mean anything involving digital signatures? Like either they are digital signatures themselves or they are covered by a digital signature (like Adobe Acrobat Sign usually does)?
In that case you are out of luck if you want to keep those signatures valid: digital signatures contain a hash of the bytes of the signed file. Any shrinking of the document changes that hash and so invalidates the signature.
Otherwise, i.e. if you mean something else by "e-signature", please explain.
