Professional color to grayscale conversion with multiple algorithms
No conversions yet. Start converting colors to see history.
Uses perceptual weights: 0.299×R + 0.587×G + 0.114×B. This matches human eye sensitivity and produces the most natural grayscale images.
Averages RGB values: (R + G + B) ÷ 3. Simple but doesn't account for human perception differences between colors.
Uses (max(R,G,B) + min(R,G,B)) ÷ 2. Preserves brightness relationships but may lose contrast.
Uses individual R, G, or B channels. Green channel often produces best results due to eye sensitivity.
Uses the highest RGB value. Creates bright, high-contrast grayscale images with preserved highlights.
Uses the lowest RGB value. Creates darker grayscale images that emphasize shadows and depth.
Grayscale conversion is essential for:
