Need change background colouring PDF
Hello
I have a Lego instruction manual for Ghostbusters Fire Headquarters as a PDF, unfortunately the background is black, as is the printed manual, makes it difficult to read.....need to change the background to white..
tried Acrobat PRO, Edit, preferences, accessibility, but although I can change the background to white, I only have a save as option which doesn’t save the changes. If the saved file is opened in a browser it’s not changed.
help please, quite happy to use a free PDF editor if it will do what I want, but curious why acrobat doesn’t save changes.
thanks
