Jigsaw Puzzle Maker
Choose, drop or paste a picture and this maker cuts it into a real jigsaw: every shared edge is one seeded curve, so each tab fits its neighbour's blank exactly, and the same picture, piece count and seed always give the same cut. Pick pieces up from the tray and place them by click, tap, mouse drag or keyboard; each piece fits only its own slot. The picture is read in your browser tab and never uploaded, progress saves on this device without the picture, and the cut sheet prints or downloads as a PNG.
Your picture
PNG, JPEG, GIF, WebP or BMP up to 12 MP. Drop it here or paste it. It stays on this device.
Empty slots show only the grid.

How the pieces are cut. Every shared edge is one seeded curve that both neighbouring pieces trace, so each tab fills its blank exactly. The same picture, piece count and seed always cut the same puzzle. Your picture is read in this tab and never uploaded; saved progress keeps the grid, seed, placements and a fingerprint of the file, not the picture.
Common questions
- How do I make a jigsaw puzzle from my own photo?
- Choose a picture, or drop or paste a PNG, JPEG, GIF, WebP or BMP file, then set the number of pieces, pick a difficulty and press Make puzzle. Before you make it, the board previews the cut lines on your picture. Making the puzzle moves every piece into a tray in a seeded shuffled order, and the board starts empty.
- How many pieces can the puzzle have?
- You ask for 4 to 300. The maker picks the grid that best balances staying close to that count with keeping the pieces near square for your picture's shape, at least 2 × 2 and never under 8 pixels a side. A 4000 × 3000 photo at 48 pieces gives 8 × 6, and a 1920 × 1080 picture at 300 gives 23 × 13, which is 299 pieces. The line under the settings shows the exact grid before you make it.
- How big can the picture be?
- Up to 12,582,912 pixels (12 × 1024 × 1024), which fits a 12 MP phone photo at 4032 × 3024, with each side from 32 to 16,384 pixels. The size is read from the file's header first, so a larger picture is refused before it is decoded, and the message suggests a size that fits. Pieces are cut from a working copy whose longest side is at most 2,400 pixels.
- Is my picture uploaded or saved anywhere?
- No. The picture is read in this browser tab and never sent anywhere, and there is no sharing link. This browser's local storage keeps one saved puzzle: its grid, seed, difficulty, placed pieces, piece turns, tray order and number of tries, your last piece count and difficulty settings, and a fingerprint of the file (its length, a 32-bit checksum and its pixel size). To continue, choose the same picture file again; an edited or re-saved copy has a different fingerprint and cannot continue that save. Making a new puzzle replaces the saved one.
- Can I play with a keyboard or on a phone?
- Yes. With a keyboard, the arrow keys move through the loose pieces and Enter picks one up; on the board, the arrows move between slots, Enter places the piece, Escape puts it back and R turns it when pieces start turned. On a touch screen, tap a piece and then tap its slot; with a mouse or pen you can also drag a piece onto its slot. On narrow screens every board slot stays at least 44 pixels and the board scrolls inside its own frame.
- What do the difficulty levels change?
- Guide picture shows a faint copy of your picture under the board. No guide shows only the grid. No guide, turned pieces also starts pieces turned by quarter turns, and a piece has to be rotated upright before it fits its slot.
- Can I print it and cut out a real puzzle?
- Yes. Print cut sheet opens your browser's print dialog with your picture and every cut line drawn in white over a dark outline. Download cut sheet (PNG) saves the same sheet at the working copy's size. Print it on card and cut along the lines.
- What does the seed do?
- The seed sets the tab shapes, the order of the pieces in the tray and, with turned pieces, how each piece starts turned. The same picture, piece count and seed always cut the same puzzle. A new seed is drawn each time the page opens and New seed draws another; type a seed to repeat a cut.
