Question 1

What does the SVG export contain?

Accepted Answer

Two color-separated layers: a cut layer (red strokes by default) for the outer border and every interior jigsaw seam, and an engrave layer containing your uploaded image embedded as a raster bitmap. Most laser software (LightBurn, LaserGRBL, xTool Creative Space, Glowforge) treats different colors as different operations.

Question 2

What thickness of material should I use?

Accepted Answer

3mm plywood or MDF is the sweet spot for jigsaw puzzles — thick enough to feel solid in hand, thin enough to cut quickly with most diode and CO₂ lasers. For finer pieces (under 8mm), drop to 2mm to keep the kerf from eating away the tabs.

Question 3

Will the pieces actually interlock?

Accepted Answer

Yes — the tab geometry uses classic narrow-neck / wide-head shapes so adjacent pieces snap together. Tab direction is randomized so neighboring edges always have one knob and one socket. Watch your laser kerf: if your machine cuts a wide line, increase the piece size so the kerf doesn't loosen the fit.

Question 4

Do I need to create an account?

No. The Jigsaw Puzzle Designer runs entirely in your browser. No sign-up, no tracking, and your photo never leaves your device.
