Browser-based STL

Prepare a lithophane from your photo.

Upload an image, adjust the key print dimensions, preview before export, and download an STL file for your slicer.

The preview runs in your browser and does not save your image.

The generator creates the STL file locally in your browser from your preview. It does not save designs or share anything to a gallery.
