PDF Dark Mode

Dark mode toggle for PDF files.

This extension is currently in beta, so it may have bugs. It serves to create a Dark Mode for PDF files viewed in Chrome. Due to the limitations of Chrome's PDF viewer, it can only invert colors and apply broad filters. Hotkeys: Alt+Shift+D = Toggle Dark Mode Alt+Shift+S = Toggle Sepia The app currently enables a standard inversion mode, and a sepia mode that gives off "kindle dark mode" vibes. It is entirely open source, so please feel free to suggest features, report bugs, or make contributions using the support URL on this page. Support future updates by donating at https://buymeacoffee.com/adamcodes Update Beta 0.5: Fixed a bug where no PDF would be detected due to how Chrome now renders PDFs as of December 2025. Added hotkeys to toggle dark and sepia modes. Please try them out! Thanks to those of you who emailed me to let me know something broke :)
