Use this page to convert PDF to grayscale for cheaper printing, and keep real text selectable where the file allows.
Files stay on this device. Nothing is uploaded.
Keep text sharp changes the colors inside the page itself: colored text, lines and shapes become the matching shade of gray, and color pictures become grayscale pictures. Text stays real text, so it prints crisply and you can still search and copy it.
A few things cannot be changed that way, such as color gradients and spot colors. When a page has them, just that page is turned into a grayscale picture, and the result tells you which pages.
Convert everything to images always works, but every page becomes a picture, so text can no longer be selected or searched.
