The pixelation effect works by downsampling the image to a tiny grid (one pixel per block) then scaling it back up with nearest-neighbor sampling — giving the classic mosaic/pixel-art look. Larger block sizes create more extreme pixelation. Use it to censor faces, create retro game graphics, or build pixel-art effects. For color effects, try Grayscale or Color Inverter.
