Nonogram Maker illustration

Nonogram Maker

Draw a picture on a pixel grid — or start from a random pattern — and the tool computes the row and column number clues that define a nonogram (also known as picross, griddler or hanjie). Solve it on the page by filling and marking cells, print it, export PNG/SVG or publish an interactive embed.

Runs 100% in your browser — your puzzles never leave your device.

Notes

  • Grid sizes from 5×5 to 20×20; the live clue panel updates as you draw.
  • A good nonogram should be solvable line by line — very sparse or very dense pictures can be ambiguous, so the tool warns about empty rows and columns.
  • Runs 100% in your browser — your words and puzzles never leave your device unless you publish an embed.
