About this tool

Flip the colors of a PDF so bright white backgrounds turn dark and black text turns light, giving you a comfortable dark-mode reading experience. It's a relief for late-night study sessions, hours of on-screen reading, and viewing in dim surroundings where a glaring page would tire your eyes. Every color across all pages is inverted at once while the text stays crisp, legible, and fully selectable, so the document keeps working exactly as before. One operation transforms the whole file, instantly delivering a dark-themed version made for screens. Privacy never enters the equation, because the inversion is computed locally within your browser and no file is uploaded to any server, so your documents stay yours. The PDF you get back retains its original quality and is downloadable straight away. Built for students reading after dark, professionals reviewing on a monitor, and anyone who simply prefers dark mode for easier reading.
