What are you using for the signature appearance?
I am using standard signature:
[ image of digital ID removed by forum host for security reasons ]
I did this before with Acrobat 8 without this big file size increase.
I am using my business PKI card to sign the documents.
i just want to say that i have the same problem - and we got customer complaints on this fact. It makes no difference if you insert a picture into your signature or what ever. With two signatures on a form the file size goes up from 70k to 3MB and with the second up to 6MB - no other changes will be done - only the signature
Help would be GREAT.
Finally I found the solution.
The file size increase is a result of the embedded information used for long-term signature validation.
If you do not need this feature, you can turn it off:
Preferences > Security > Advanced Preferences > Creation tab
disable "Include Signature’s Revocation"
Thanks a lot - That's the solution !!!!!!!!!!
