Frequently asked questions
Does grayscale reduce file size?
Often slightly, since color variation drops — run the result through the Image Compressor for real savings.
Is grayscale the same as black and white?
In everyday use, yes. Technically grayscale has many shades of gray, while true black-and-white (1-bit) has only two tones.
Can I convert back to color?
No — color information is discarded during conversion, so keep your original file.
