How to convert an image to a lithophane

Drop a JPG or PNG above.
Adjust width, thickness and frame; check the backlit preview.
Download the STL (or 3MF) and slice it with 100% infill.

Which images work best

Portraits and landscapes with clear light and dark areas.
Not too much fine texture: details smaller than about 0.4 mm can't be printed.
Transparent PNG areas are treated as white (thinnest).

For a multicolour print instead of a light-through relief, use image to 3MF.

Frequently asked questions

What resolution should my image have?

About 500–1000 pixels across is plenty: at 0.2 mm detail a 100 mm lithophane uses about 470 points across. Larger images are resampled.
