Why It Matters
Most PDFs are designed with bright backgrounds that can cause eye strain during long reading sessions, especially in dark environments. Traditional dark-mode browser extensions often invert colors indiscriminately, making images, charts, and diagrams difficult to interpret. By intelligently applying dark themes while preserving visual content and processing files entirely on-device, this tool provides a more comfortable and privacy-focused reading experience.
Read PDFs More Comfortably
Convert documents into eye-friendly dark mode themes, preserve image quality, and keep your files completely private with a browser-based PDF reader designed for comfortable reading day or night.
