About PDF Dark Reader

Yes, this extension works for lecture slides on school websites! Tired of bright white PDFs while studying? PDF Dark Reader adds a toggleable dark theme to PDF.js viewers embedded on school and university websites - no more eye strain. Features: - Toggle dark mode per tab, or enable Persistent Mode to apply it automatically on every PDF.js viewer you visit. - Won't interfere with your browser's existing dark theme or other dark mode extensions. - Pairs well with a general dark mode extension for a complete dark experience. Note: Targets PDF.js viewers hosted on websites only. Does not affect PDFs opened directly from your device in the browser's built-in viewer.
