Lightning Brain Color2Gray

Sometimes you want a particular picture to be output as a grayscale image, yet the original image is in color.

You could open the image in Adobe® Photoshop® and convert it to grayscale, but instead you can also use this plug-in. When using this tool, the original image is not changed and remains in color, yet it is output as a grayscale image.

When outputting in CMYK, the gray image will only render on the black (K) plate.

It works best for JPEG and TIFF images. As far as we know, complex, multi-layered Photoshop images don't always work - so you might want to stick to JPEG or TIFF.
