GPU-rendered dots with adjustable cell size and screen angle — not a blur filter.
One-color film or four-channel C/M/Y/K separations at proper 15°/75°/0°/45° angles.
Round, square, diamond, line. Knockout and distress for worn, vintage prints.
Live WebGL preview as you tweak — watermarked until you export.
Clean PNG with true transparency, sized for your film. We never store your art.
Free to try. Pro & Studio unlock full-res, CMYK, batch, and commercial use.
Upload, dial in the dots, export. That's it.
