I received a PDF in which the font was all grey, making it difficult to read. I'd like to convert it all to black, but seem to be able to only do this lin-by-line, which takes way too long!

Are there any known methods to universally change the font color in Nitro Pro 9.5.4.22?

Thank you in advance for any help you can provide!
