When to use Grayscale Image
Create a grayscale PNG for a monochrome illustration or photo. The output keeps the original pixel dimensions.
Practical example
A 120 × 80 color photo exports as a 120 × 80 grayscale PNG.
Is this the same as a black-and-white threshold?
No. Grayscale preserves shades between black and white rather than forcing every pixel to one of two colors. This is not a print color-profile conversion.
