About Grayscale Conversion

Unlike simple black and white conversion, grayscale preserves much more detail by using various shades of gray to represent luminance (brightness). Our tool uses a weighted luminance method that better matches human perception of color brightness.

Grayscale images are commonly used in professional photography, print publications, and when you want to emphasize composition, texture, and form over color. The luminance formula we use (R*0.299 + G*0.587 + B*0.114) gives green colors more weight in the conversion, matching how human eyes perceive brightness.
