Can I convert back to color after making an image grayscale?

No. Converting to grayscale permanently removes color information. Keep the original color image if you may need it later.

Will grayscale reduce file size?

The pixel dimensions stay the same, but grayscale images contain less color data. Saving as a single-channel format can reduce file size.

Is grayscale the same as black and white?

Grayscale includes all shades from white to black. The "Black & White" tool in FlexKit uses a threshold to produce pure black or pure white pixels only.

What is the difference between grayscale and desaturating in Photoshop?

The grayscale conversion uses a luminance-weighted formula (similar to desaturate). The result is nearly identical.
