About Invert Colors
What Color Inversion Does
Color inversion flips every pixel to its opposite on the color spectrum. White becomes black, black becomes white, and every color in between shifts to its complement. It’s the same effect as a photographic negative.
OxygenPDF renders each page, inverts the pixel data, and rebuilds the PDF. A live preview shows the inverted result on your actual pages before you commit. Everything runs in your browser.
When Color Inversion Is Useful
Inverting colors isn’t something you do every day, but when you need it, nothing else will do.
Dark Mode Reading
Invert a white-background PDF to dark background with light text. Easier on the eyes during long reading sessions or in low-light environments.
Toner Savings
A document with a dark background and light text wastes toner. Invert it to white background before printing.
Design & Art
Graphic designers use color inversion to explore alternative color schemes or create negative-image effects for visual projects.
Visual Accessibility
Some people with visual impairments find inverted color schemes easier to read. Inversion can improve contrast for certain content.
How It Compares
Color inversion for PDFs is uncommon in online tools. Most require a desktop application.
