Convert an image to black and white
Grayscale lends a classic, elegant feel to any photo, and it solves real problems in printing, design and minimalist compositions too. Here the conversion of any image to black and white runs right in your browser.
The calculation starts from each pixel's original colours to land on the right shade of grey, keeping the light and shadows as they were. Use it to make monochrome versions of your photos, prepare files for a grayscale printer, or just try a different look.
Since everything is processed on your own device, the image never leaves for any server. Load the photo and download the black-and-white version within seconds.
