How does the grayscale converter work?

Our tool converts color images to grayscale by calculating the luminance of each pixel using the standard formula (0.299×R + 0.587×G + 0.114×B). This preserves the perceived brightness and creates natural-looking black and white images.

What's the difference between grayscale and black & white?

Grayscale images contain 256 shades of gray, creating smooth transitions and preserving detail. Pure black & white has only two colors. Our grayscale converter creates true grayscale images with full tonal range.

Does grayscale conversion affect image quality?

No! Our grayscale converter maintains the original image resolution and quality. File sizes may be slightly reduced since color information is removed, but visual quality remains excellent.

What formats does the grayscale tool support?

We support JPG, PNG, and WEBP formats. PNG transparency is preserved during conversion, making it perfect for logos and graphics with transparent backgrounds.

Is the grayscale converter free to use?

Yes! Our grayscale image tool is completely free with no watermarks, registration requirements, or usage limits. Convert as many images to grayscale as you need.

Can I use grayscale images commercially?

Absolutely! Once you convert images to grayscale with our tool, you retain all rights to use them for any purpose, including commercial projects.
