Someone I support has a pdf with a too dark background and is having trouble reading it. By using the controls in Okular I can make it black font on white background, and its perfect, easy to read and straightforward.
However, I can't figure out how to either export a copy with the changes, or make the same changes in some other package.
To make the changes I used the accessibility options in Okular's configure control, and did convert to black and white, then threshold about 75% and contrast 100%. Okular remembers to apply this on my machine when the file is opened, but how to make the changes to the file itself so that other readers show the same thing?
Any suggestions?

There doesn't appear to be any useful Export options in Okular so can't you print it again to a PDF?

Have you tried Libre Office. You can import and read PDF's in Write and there is an option to edit them in Draw. I tried out changing text and background colour, and it can be done in Draw, then exported as a new PDF.
