A grayscale image is a monochromatic photo that contains shades of gray between pure black and pure white.

Our converter uses the standard NTSC colorimetry formula to convert color coordinates to gray coordinates seamlessly, preserving visual contrast.

While frequently used interchangeably, they refer to different formats:
- Grayscale: Stores 256 different shades of gray (8-bit depth), preserving soft transitions and mid-tones.
- Black & White (Monochrome Binary): Uses only 2 colors: absolute white and absolute black (1-bit depth). Perfect for line art, signatures, and high-contrast stencils.
