Frequently Asked Questions
How do I make an image black and white?
Upload your image using the tool above. The grayscale conversion is applied automatically using the luminance formula (0.299R + 0.587G + 0.114B). Download in PNG, JPG, or WEBP.
What is the difference between grayscale and black and white?
Grayscale includes the full range of gray tones from white to black. True black and white (1-bit) only uses pure black and pure white pixels. This tool creates grayscale images.

Yes. This tool converts any color image to grayscale directly in your browser. No software installation, no Photoshop, and no file uploads to a server.
