# Photo to STL Converter — Relief & Lithophane Generator

Canonical page: https://imageto3dprint.com/photo-to-stl

Turn a photo into a brightness-based relief or lithophane. Set size and depth, preview the actual 3D surface, and download STL, 3MF, or OBJ.

A favorite face. A place you love. Make a brightness-based relief or a glowing lithophane, then download the model for your printer.

Choose a relief to turn image brightness into shallow height, or a lithophane to turn dark tones into greater material thickness. Both create closed printable surfaces with a flat back. Neither reconstructs a complete figurine or infers anatomical depth.

## Turn tone into depth

Relief mode uses brightness to create a shallow height map attached to a base.

## Let the image glow

Lithophane mode makes dark pixels thicker and light pixels thinner so backlighting reveals the picture.

## Preview and download

Adjust dimensions, depth, and smoothing. Inspect the generated surface and download STL, 3MF, or OBJ.

## Tips

- Use the original photo instead of a screenshot.
- Choose a subject that stands apart from the background.
- For portraits, look for soft, even lighting on the face.

## Frequently asked questions

### Can I convert my photo today?

Artwork, reliefs, and lithophanes support STL, 3MF, OBJ, STEP, and GLB. Photo surfaces use faceted CAD solids.

### Will a photo of my dog become a figurine?

No. Reliefs use image brightness to create shallow surfaces. This does not reconstruct a dog’s anatomy or hidden geometry. Full AI generation remains a separate future feature.
