About this tool
Invert every color in a picture to create a photographic negative. It is useful for checking contrast, making dark-mode versions of black-on-white graphics, scanning negatives and creating artistic effects.
Tick Black & white to produce a monochrome negative. Because inversion is mathematical, applying it twice returns the original image exactly.
