Turn a photo into numbered painting regions, a color key and a reference sheet.
Use the guide alongside the working tool.
Open Photo to Paint-by-Numbers →Start with a good source
Add a photo or try the sample. The photo keeps its original proportions.
Design and review
Choose colors, outline detail and smoothing. Review the numbered painting, coloring-style outline, color reference and key.
Print or export
Download all four sheets as PDF or save one sheet as SVG/PNG.
Privacy and practical limits
Everything is generated on your device; photos, names and designs are not uploaded. No AI model or cloud processing is used. JPG, PNG and WebP: up to 20 MB and 16 MP per photo, 50 MB combined, four photos for a book and one for other tools. Photos are normalized to a 640-pixel working copy; complex textures and low contrast may need different settings. SVG and PNG export the selected sheet; PDF includes every sheet, including separate solutions. PDF artwork is rasterized at approximately 200 dpi on A4. SVG contains vector shapes/text and embedded pixels for photo puzzles; original metadata is not retained. Smaller inputs may be needed on mobile. Cancel stops the active worker; changing controls discards stale results. Uses the same alpha compositing, grayscale smoothing and Sobel outline technique as Photo to Coloring Page. Perceptual Lab color clustering runs at a proportional 360–640-pixel working edge without upscaling. Detected photo edges are retained; only isolated one-pixel quantization noise away from edges is removed. Labels are placed inside regions with enough room to print legibly; tiny details use the color reference. Very textured inputs may need fewer colors or less detail. The color-key counts describe analysis pixels, not paint quantities. This does not identify subjects or invent missing detail.
