What You Can Create

From wall art to custom tools, here is what makers create with this image to STL converter.

3D Photo Reliefs

Turn any portrait, landscape, or artwork into an embossed 3D panel. The heightmap mode maps pixel brightness to physical depth, creating detailed reliefs perfect for wall art, coasters, and decorative tiles.

Lithophanes

Convert your photos into thin translucent panels. When backlit, the varying thickness reveals your image in stunning detail. Makes incredible personalized lamps, night lights, and window displays.

Cookie Cutters

Upload a silhouette or simple shape and get a custom cookie cutter STL. Perfect for themed parties, holidays, and personalized gifts.

Logo & Icon Extrusions

Upload your SVG logo and extrude it into a solid 3D object. Ideal for custom signage, desk ornaments, keychains, and brand merchandise.

Custom Badges & Signs

Create raised lettering, embossed text, and dimensional signage. Use the text-to-3D tool for quick typography or upload complex SVG designs.

Topographic & Terrain Maps

Convert grayscale height maps, elevation data, or satellite imagery into 3D terrain models. Adjust the height scale for dramatic mountain ranges or subtle landscape contours.

Custom Jewelry & Pendants

Create personalized pendants, charms, and medallions from photos and designs. Convert a meaningful symbol, initials, or a small photo into wearable 3D printed jewelry. Use resin printing for finer detail on small pieces.

Stamps & Embossing Tools

Design custom stamps for clay, fondant, soap, leather, and paper crafts. Use the invert toggle to create the negative impression, then print with flexible filament or hard PLA depending on your material.

Molds for Casting & Chocolates

Create food-safe molds for chocolates, candies, ice cubes, and resin casting. Convert your design to a negative relief, print the mold, and cast your creations. Use food-safe filament if making edible items.

12 — Choosing a mode

Which conversion mode should I pick?

The fastest way to a good result is picking the right mode before you touch a slider. Here is how the three modes differ in practice, and how to tell within seconds which one your image needs.

How do I know if my image is high-contrast enough for a good relief?

Squint at it. If the main subject still reads clearly when half-closed, it will convert well. Relief depth is driven purely by tonal separation, so a portrait lit from one side produces far more depth than a flat, evenly lit snapshot. If the result looks shallow, raise contrast in a photo editor before uploading rather than pushing the height slider to its limit — extreme height on a low-contrast source just amplifies noise.

My SVG has gradients and text effects. Will extrusion handle it?

Extrusion works on geometry, not paint, so gradients, drop shadows, and raster filters are ignored entirely — only the underlying filled shapes are extruded. Convert text to outlines first, and flatten any effects before export. If the file still fails to extrude, the tool falls back to heightmap mode automatically, which rasterises the design and produces a usable model at the cost of crisp edges.

What determines the physical size of the printed part?

Only your slicer. The STL stores geometry with no unit system attached, so a model exported here has no inherent millimetres. Scale it in Cura, PrusaSlicer, or Bambu Studio to match your build plate. That also means the 512px processing resolution is not a size limit — a 512px relief scaled to 200 mm is simply coarser per millimetre than the same relief printed at 80 mm.

Which is better for a lithophane: thicker or thinner?

Thicker prints hold more contrast but block more light and take longer. Start around 3 mm maximum thickness with roughly a 0.8 mm floor, then print a small test tile before committing to a full-size panel. The floor thickness matters more than the maximum — drop it too low and the panel becomes fragile and prone to light bleed between adjacent areas.

Why is my STL file unexpectedly huge?

Triangle count is the cause, and triangle count is set by your smoothness setting. A 512px heightmap at maximum detail generates a dense mesh where a simplified one would look nearly identical once printed. Raise smoothness for geometric subjects and logos; keep it low only for fine photographic texture. Reducing triangle count also shortens slicing time noticeably.

Can I edit the model after converting, without CAD software?

Yes, within limits. The heightmap editor lets you crop, invert, and reshape the depth profile before export, which covers most corrective work. For anything structural — adding a base, hollowing, drilling a mounting hole — bring the STL into a free slicer or mesh tool. Because the output is a standard watertight mesh, it imports cleanly into Blender, MeshLab, or Tinkercad without repair.
