Frequently Asked Questions
What is the difference between grayscale and black & white?
Grayscale preserves all shades of gray, while black & white converts pixels to pure black or white based on a threshold value.
How does the threshold work for black & white mode?
The threshold determines the cutoff point. Pixels lighter than the threshold become white, darker pixels become black. Default is 128 (midpoint).
Will my images be uploaded to a server?
