PDF Dark Reader: DarkReader

PDF reader with a real dark mode. Darkens paper and text, leaves photos and charts as they are. Works fully offline with no internet permission.

DARK MODE THAT KEEPS IMAGES INTACT
Most dark PDF viewers invert the whole page, turning photos into negatives. This one inverts only paper and text. Images, diagrams and coloured charts stay readable.
