A pdf looks like it was made from photos that were then saved as a pdf. It is text only and there is no color (other than highlighted text) but the background of each page is dark. One page is attached.
Is there a way to lighten the background? If the background cannot be lightened, is there a way to lighten the whole document (so the text would be lighter as well)? If so, can that only be done page by page or can all pages be lightened at once?
Also, on some of the pages (but not all) the images do not cover the full page. I know that I can resize each image individually but does there happen to be a setting that would resize all of the images at the same time? I doubt there is such as setting but thought it worth asking.
Finally, while the file is only 35 pages, it is about 20 megs. Is there a way to reduce the size?
