FAQ

What are levels?
How many distinct shades of gray are used. Lower (4) = posterized blocky look; higher (64) = closer to continuous.
Does converting to grayscale upload my image?
No. Conversion happens entirely in your browser — your image never leaves your device.
What's the difference between continuous and quantized grayscale?
Continuous uses smooth, full-range shading. Quantized limits output to a set number of levels (e.g., 4, 16, 64) for a poster-style look.
