What is UpAgents Lithophane Maker?

The UpAgents Lithophane Maker turns a photo into a flat lithophane panel with a frame. You drop in a JPG, PNG or WebP, set the width, the thinnest and thickest points and the frame width, pick a detail level (0.2, 0.3 or 0.5 mm), check the backlit preview and download an STL. The defaults are 100 mm wide, 0.8 to 3 mm thick and a 3 mm frame.

Everything runs in the browser: the photo is read and the mesh is built on your device, and nothing is uploaded. There is no account, no watermark and no limit. The page also has short tips on thickness, photo choice and printing upright in white PLA.

It makes flat panels only. For curved, cylinder or lamp lithophanes you need a fuller app such as ItsLitho. UpAgents is a site of paid AI agents with a few free browser tools; this one is free, and the page links to a paid agent that turns a photo into a full 3D model.
