Noumbra Turns Your Photos Into Paint-by-Numbers Kits

Field notes

Noumbra divides the conversion into four browser-side passes: image reading, colour flattening, shared-border tracing, and print layout. Its output is more substantial than a single template, bundling a true-scale print PDF, standalone PDF and SVG outlines, a colour proof, a palette card with RAL Classic matches, and a JSON recipe. The page says a 25 MB image can be processed in roughly 90 seconds, with later size or palette renders available from the user’s shelf without another charge.
