About this tool
Color by Number Generator turns any photo into a ready-to-print painting sheet — the kind you'd find in a craft store, but made from your own pictures.
How it works
Drop in any PNG, JPG, WEBP, or GIF. Your image never leaves your device — all processing happens locally in your browser.
Choose how many colors you want, cell size, sharpness, and more. The palette editor lets you swap or remove individual colors.
Export a high-resolution PNG for screens or a crisp SVG for printing. The outline sheet is ready to paint right away.
Privacy first
Your photos are processed entirely in JavaScript running in your browser tab. Nothing is uploaded, stored, or transmitted to any server. Once you close the tab the image is gone. We collect anonymous, aggregate page-view statistics (no cookies, no cross-site tracking) and serve ads only when you have given explicit cookie consent.
Who it's for
- Parents and teachers looking for personalised craft activities
