DarkMode PDF Viewer

A custom PDF viewer that forces clean, consistent Dark Mode on all PDFs.

DarkMode PDF Viewer replaces the default PDF viewer with a clean, comfortable Dark Mode reader designed for night-time reading. This extension fixes the biggest problem with reading PDFs in your browser: the blinding white background. DarkMode PDF Viewer applies a true dark theme to every PDF you open, using a custom PDF.js-powered viewer that loads quickly and stays consistent across all websites. ✔ True Dark Mode for all PDFs ✔ Lightweight and fast – opens instantly ✔ Zero ads, zero tracking, zero data collection ✔ Works with any PDF opened in the browser ✔ Clean UI with simple zoom controls ✔ Perfect for studying, coding PDFs, academic reading, and long documents ✔ Does NOT affect other websites or interfere with Chrome's default theme 💡 Why this extension is better Most dark mode extensions fail on PDFs because Chrome blocks styling on its built-in viewer. This extension solves it by using a fully custom PDF viewer, ensuring perfect Dark Mode on every single document. 🛡 Privacy • No data collection • No analytics • No external servers • Everything runs locally on your browser If you read PDFs at night or spend long hours studying documents, DarkMode PDF Viewer will instantly reduce eye strain and make reading far more comfortable. DarkMode PDF Viewer is simple, clean, fast, and built for people who read a LOT of PDFs. Try it once and you’ll never go back to the blinding white default viewer again.
