Each page is rendered with inverted colors. This rasterizes pages, so text becomes part of the image.

When to invert PDF colors
Inverted, light-on-dark pages are far easier on the eyes in low light, which makes this a favorite for reading manuals and long documents at night.
It also works well on e-ink readers and OLED screens, where dark backgrounds reduce glare and save battery. Printing stays possible too: the inverted file prints as a negative, which some workflows use deliberately.
