DarkPaper

Read PDFs in true dark mode — recolored, not inverted. Text stays sharp, figures keep their colors, and you can share the dark version as a real PDF.

DarkPaper re-renders your PDFs for reading in the dark. Instead of inverting the page like a screen filter, it recolors the document itself — text, figures, and fills — so pages stay crisp on a true dark background and a blue line stays blue at night.

READING • Five palettes: Original, Black, Soft, Sepia, Navy • Text stays vector-sharp — no raster inversion, no smearing • Figures keep their meaning: heatmaps still read hot, plots keep their colors

LIBRARY • Open PDFs from Files or any app's share sheet • Continue reading where you left off

SHARE IT DARK • Export the dark rendering as a real PDF — it looks the same everywhere

PRICE • Your first three documents are free, then a free week — no card, no account, nothing to cancel • One purchase unlocks DarkPaper forever. No subscription.

PRIVATE BY DESIGN • No accounts, no analytics, no tracking — your documents never leave your device
