I am using Adobe Acrobat Pro 2015.006.30121 in Windows 10.
I need to submit documents with my digital signature to a court. The court uses a program that requires the document to be PDF Version of 1.5 or lower. I save my pdf document using File/Save As Other/Reduced Size PDF. When I look at File/Properties/Document Properties Description the PDF Version is 1.5. However, after I apply my Acrobat digital signature the PDF Version is increased to 1.6. Now the document is uneditable so I cannot do another File/Save As Other to reduce the PDF Version back to 1.5. How do I change a setting such that applying my digital signature does NOT increase the PDF Version?
