Grayscale conversion transforms color images into black and white by removing color information while preserving luminance (brightness) values. Our tool uses the standard luminance formula (0.299×R + 0.587×G + 0.114×B) which provides the most visually accurate grayscale conversion by accounting for human eye sensitivity to different colors.
