DarkPaper
True dark mode for your PDFs — on iPhone and iPad.
What is DarkPaper?
DarkPaper re-renders PDFs for reading in the dark. Instead of crudely inverting the page like a screen filter, it recolors the document itself — text, figures, and fills — so papers stay crisp and readable on a true dark background. Pick from Black, Soft, Sepia, or Navy palettes, and share the dark version as a real PDF that looks the same anywhere.
How do I open a PDF?
- Tap Open PDF in the app and pick a file, or
- use the iOS Share sheet from any app (Files, Safari, Mail, …) and choose DarkPaper.
Imported documents stay in your library so you can reopen them instantly.
What's free, what's paid?
Your first three documents are free, no questions asked. After that you can start a free week — no card, no account, nothing to cancel. When the week is over, a single one-time purchase unlocks DarkPaper forever, on every device signed into your Apple ID.
Already purchased? Open the unlock sheet and tap Restore purchase.
Do my documents leave my device?
No. DarkPaper works entirely on your device — nothing is uploaded, ever. See the privacy policy for the full story (it's short).
