Picture to Color by Number
Turn a picture into a color by number sheet, right in your browser. This paint by numbers generator reduces a photo to flat numbered blocks and builds the number-to-color key beside it. Free, no sign-up, and your photo never leaves your device.

How it works
- Choose a photo. It is read into the page with your browser and never sent anywhere.
- The photo is blurred slightly, then its colors are clustered into the number of colors you picked.
- Every pixel is switched to the nearest of those colors, and small specks are merged into their neighbours.
- Connected areas of one colour become the blocks. Each block gets a number, and the key on the right tells you which colour that number means.
Picture to color by number
Any picture works — a pet, a landscape, a family photo. Photos with a few large, clearly different areas give the cleanest blocks; very busy or grainy photos produce more small pieces, which is what Smoothing and Block cleanup are for.
Color by number generator for printing
The download is a single PNG with the numbered artwork and the colour key side by side, so the sheet is ready to print on one page. Raise the number of colours for a detailed picture, or lower it to six or eight for young children.
