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.
