FAQ
What is the difference between grayscale and black-and-white?
Grayscale keeps 256 shades from black to white — it is not a pure binary image. You get rich layered black-and-white photos.
Can I restore colors after conversion?
No — color information is lost. Keep your original file safe.
What does grayscale intensity mean?
It controls the desaturation level. 100% is full black-and-white, 50% keeps some color for a partially faded look.
