Convert any PDF to dark mode — fully in your browser
Launch week is coming up. This startup will launch on June 28, 2026 and start accepting upvotes then.
PDF Dark turns any PDF into a real dark-mode file you can download, share, and reread anywhere. The conversion happens entirely in your browser — your file never touches a server. A saturation-based algorithm preserves photos and charts in original colors while darkening the rest. Free, MIT-licensed, no signup, no ads.
