PDF Color Inversion Guide

Why Invert PDF Colors?

PDF color inversion is essential for creating dark mode versions of documents, reducing eye strain during low-light reading, and improving accessibility for users who prefer dark themes. Inverted PDFs are easier to read on screens in dark environments. Our tool uses advanced canvas-based pixel inversion to ensure accurate color transformation while maintaining document quality and readability across all PDF viewers.

Color Inversion Technology

Our color inversion process uses HTML5 canvas technology to render each PDF page and invert colors at the pixel level. This ensures accurate color transformation where white backgrounds become black, black text becomes white, and all colors are properly inverted. This pixel-level inversion creates true dark mode PDFs that work perfectly in any PDF viewer, providing consistent dark theme experience across all devices and applications.
