A PDF reader for Mac, iPhone, and iPad that darkens text and pages while preserving the original appearance of embedded images.

Why it surfaced

Lucerna reads a PDF’s content stream to find where images sit, then leaves those images intact instead of turning photographs, charts, and diagrams into negatives. It also builds a folder-based library, remembers exact reading positions, separates bookmarks from selected passages, and offers reflow on iPhone and iPad—an unusually deliberate answer to the fourth hour of reading.
