Convert images to black and white (grayscale)
Turning a color photo into grayscale gives it a classic, editorial look, highlights shapes and textures and also helps save ink when printing. The conversion takes one click and preserves the original detail and resolution.
The tool accepts several images at once and is useful both for photography and for preparing documents for printing.
