Dark-mode any PDF for night reading
A full-page overlay inverts page colours while text stays selectable. Best for reading — keep your original for archiving and printing.
Private by design
Color inversion renders locally in your browser, so late night reading of medical reports and long contracts never sends a page to a server.

Frequently asked questions
Does inverting affect images?
Everything on the page is inverted, including images — useful for reading, not for archiving originals.
Can I invert only some pages?
Not yet — inverting applies to every page; split out the pages you want first, then invert that file.
