Is there a way to flatten a pdf and keep the E-signature field ?
Thanks in advance for you answer.
No. Flattening will convert any signature you applied to a static image. In fact, Acrobat doesn't allow you to flatten a signed file. The only way to do it is to print it to a PDF printer, which is not advised in any case.
Why is it not advised. Aren't you wanting to preserve the signature?
That process does the opposite of preserving the signature. It gets rid of it.
So how does one preserve the signature.
Once a signature is done, a file cannot be changed. End of story. Flattening is changing. So, absolutely no.
What do you mean by "preserve", exactly?
Cannot be changed. Now I have a document with client's signature for submission to the government in the business process.
A digital signature can't be changed, unless you're the person who applied it. Any such attempt will invalidate it immediately.
