About this tool
Grayscale vs black and white
A grayscale image keeps every shade between black and white, so it looks like a classic monochrome photo. A true black and white image has only two tones: every pixel is either black or white, decided by a threshold. That style suits scanned documents, stamps, signatures and graphic effects.
The other sliders work like those in a photo app. Brightness lightens or darkens everything, contrast stretches the difference between light and dark, saturation controls colour intensity, and warmth shifts the image towards orange or blue.
