How to turn grayscale pdf into white pdf
I have an invoice which originally was color, I used Preflight to turn it into Grayscale, however, the gray was still too dark. Now, I need to turn it into white background. I also found out under "output preview", if I select "Text" in the show field, that works for me, but I don't know how to save it? Can anyone help me please? Thanks,
