About Grayscale Image
This tool converts any color photo into a grayscale image using a weighted luminance formula that preserves natural tonal relationships. Black and white conversion is useful for emphasizing textures and shapes, preparing images for print workflows that require single-channel output, or giving photos a timeless, classic look.
