Free Laser-Cut Jigsaw Puzzle Generator

Create custom laser-cut jigsaw puzzles from any image. Generate interlocking puzzle SVG cut files for wood, acrylic, and MDF. Any size, any piece count.

How do you make a laser-cut jigsaw puzzle from a photo?

Pick a piece count in the Puzzle Generator (quick presets run from 4 to 99 pieces, or set columns and rows), set the finished size and tab shape, and it draws interlocking cut lines with randomized knobs. Optionally drop in your photo to preview it under the cuts, then engrave the image and cut the pieces from 3 mm plywood, MDF or acrylic. The generator is free and runs in your browser.

Puzzle Generator output: interlocking cut lines for a 20-piece (5 by 4) laser-cut jigsaw puzzle with randomized knobs

Frequently Asked Questions

Is the Puzzle Generator free?

Yes — completely free, in your browser, with no account or credits required.

Can I use any photo to make a puzzle?

Yes. Upload any image; the piece grid and knob shapes generate over it automatically. Higher-resolution source images hold detail better on larger boards.

How many pieces can I generate?

Set your own board size and piece count — from a simple 4-piece puzzle up to 16 × 16 (256 pieces), on boards from 50 to 1000 mm.

What material works best?

3mm plywood or MDF cut cleanly and hold interlocking knobs well; acrylic works too. Pieces share one centre-line cut, so test the fit on scrap before a full board.
