Hi Lippy,
You didn't mention the app you're using. MS Office apps with the compression setting and MS Office Picture manager tend to use
Presets. 200ppi is a fax/print common setting and 96ppi is the screen resolution in Windows.
================
I know how to lower to 200 or 96 pdi but how do I control the percentage?>>
