About this tool

Convert any image to grayscale (black and white) with adjustable intensity. The tool uses the luminance formula (0.299R + 0.587G + 0.114B) which matches human perception of brightness — green contributes most to perceived brightness, followed by red, then blue. Adjust the intensity slider from 0% (original color) to 100% (full grayscale) for partial desaturation effects. Shows before/after comparison. Use it for creating monochrome designs, preparing images for print, and artistic effects.
