FAQ

Common questions

How does it work?

Upload an image. The browser quantizes it to a small palette, slices it into cells, assigns each cell a paint number, then renders a printable black-and-white outline with a matching color legend.

Where are my photos sent?

Nowhere. All processing runs client-side in your browser using Canvas APIs. We never see your image. If we add optional cloud features later, they'll be clearly labeled.

Can I use my own paint set?

Yes — paste hex codes or pick a starter palette (Basic Acrylic 12, Portrait Set, Landscape Set, Grayscale, High Contrast, Earth Tones). Locking the palette forces the output to map to those exact paints.

How big can I print?

Free plan caps at 11×14 in. Studio goes up to 24×36 in posters tiled across multiple Letter/A4 pages with overlap and registration marks. Pro adds mural-scale outputs.

What about commercial use?

Pro plan includes a commercial-use license. Free and Studio outputs are for personal use only.

Is this AI?

No black-box AI involved in the core pipeline. It's a deterministic image quantization + grid labeling algorithm running on your device. You get the same output every time with the same settings.

Drop an image, tweak the dials, hit print. No account required to try.
