Draw a picture on the grid and the row and column clues appear automatically. No signup, no ads, no paywall. Solve nonograms online, print them clean, or share a puzzle with a link. (Nonograms are also called picross, griddlers, or hanjie.)
Or open one to solve:
Pick a size and hit Make Nonogram. You start in Draw mode — click or drag cells to paint your picture, and the numbers along the top and left (the clues) fill in automatically from what you draw. When you like it, hit Copy share link and send it to a friend: they open it in Solve mode with an empty grid and only the clues, and work out the picture by logic — fill the squares, mark the blanks with X, and the puzzle tells you when the clues are satisfied. You can also print a clean puzzle with or without the answer.
Most nonogram and picross makers are built for KDP/book publishing and lock the maker, the export, or bulk creation behind a paid plan or a signup. This one doesn't. There's no account, no email wall, no watermark, and no limit. Every puzzle gets a shareable link that contains the whole thing — the grid size and your picture — so you can build one in seconds and text it to anyone. It works on any device, supports click-and-drag drawing and X-marking, and switches to dark mode automatically. If you've been looking for a free alternative to the paid Puzzle Maker / KDP nonogram tools, this is it.
A nonogram clue is just the lengths of the filled runs in each row and column — and getting them right by hand is tedious and error-prone. Here you simply draw the picture and the tool computes every clue exactly. When someone solves your puzzle, it checks their work against the clues (not just your exact pixels), so any logically valid solution counts. Reveal the answer anytime to see the intended picture.
Hit print and you get a clean page — the clues and the grid, with no website header, footer, or ads. Print it blank to solve on paper, or click Reveal first to print the finished picture as an answer key. Print one per kid or a set for a puzzle pack.
Logic-puzzle fans and picross lovers, classroom logic and reasoning activities, brain games for all ages, rainy-day and quiet-time activities, homemade puzzle packs and party favors, and anyone who wants to turn a little pixel drawing into a puzzle. If you searched for a free nonogram maker, a picross maker, a griddler or hanjie creator, or a no-signup alternative to the paid puzzle tools — this is it. No signup, no ads, no paywall.
