  description

  Transform your PDF reading experience with true dark mode.
  
  PDF Dark Mode uses a custom renderer to correctly invert PDF colors — without breaking images, charts, or layout.
  
  Unlike generic extensions that blindly invert everything, PDF Dark Mode intelligently distinguishes text and images to deliver a clean, natural dark theme.
  
  Key Features:
  
  • Smart Invert
  Preserves image, chart, and photo colors while darkening backgrounds and text properly.
  
  • Crystal-Clear Rendering
  Supersampling ensures sharp, crisp text at any zoom level.
  
  • Full Zoom Support
  Works seamlessly with touchpad gestures, mouse wheel, and keyboard shortcuts (Ctrl +/-).
  
  • Preserves Text Layer
  Select, copy, and search text exactly like in a normal PDF viewer.
  
  • Privacy-First
  Works entirely locally in your browser. Your PDFs never leave your device.
  
  • Works Everywhere
  Supports both local PDF files and web-based PDFs.
  
  • Easy Setup
  Simple built-in tutorial to get started in seconds.

  Transform your PDF reading experience with a custom PDF viewer built for comfortable reading.
  
  This extension replaces the default browser PDF tab with its own viewer, giving you true dark mode, smart image preservation, sepia mode and cleaner control over how PDFs look and behave.
  
  Key features:
  
  • True Dark Mode
  Darkens pages while preserving images and charts.
  
  • Smart Invert
  Keeps images, charts, and diagrams readable while preserving the overall dark theme.
  
  • Sepia Reading Mode
  Switch to a warmer sepia mode, with optional paper texture for a softer reading experience.
  
  • Sharp Rendering
  High-DPI rendering and re-rendering on zoom help keep text clear and crisp.
  
  • Works with Web and Local PDFs
  Supports both online PDFs and local files, with onboarding for file access when needed.
  
  • Per-Site Control
  Disable the extension’s visual features for specific websites without losing viewer functionality.
  
  • Privacy-First
  Runs locally in your browser. Your PDFs are not uploaded anywhere.
