What is an Invert PDF Colors tool?
An Invert PDF Colors tool flips the color values of every page so bright backgrounds become dark and text stays easy to read. It lets you convert PDF to dark mode without changing the layout, fonts, or pagination. Because everything happens locally in your browser, you get consistent results and keep sensitive documents private.
