Image to STL
Image to STL Converter
Turn any picture into a slicer-ready STL with real 3D geometry. Download and print the same afternoon.
Upload a picture
A photo, a sketch, a product shot. JPG, PNG or WEBP up to 20 MB.
Generate the mesh
AI reconstructs true volumetric geometry, not a flat heightmap.
Download the STL
Binary STL converted in your browser, ready for any slicer.
Convert an image to an STL file
Upload a JPG, PNG or WEBP and Opolyo reconstructs it as a full 3D mesh, then converts it to STL right in your browser at download time. No software to install, nothing to configure in your slicer beyond the usual.
From photo to 3D print
A photo of a figurine, a sketch of a part, a product shot: the same pipeline takes it from flat pixels to a printable model. Download the STL, slice it, and print.
AI mesh vs flat extrusion
Classic image-to-STL tools extrude a heightmap: the result is a relief, flat on the back. Opolyo generates true volumetric geometry with AI, so the model has a real back, sides and depth, ready for printing from any angle.
FAQ
Is there a free image to STL converter on Opolyo?
Generation costs credits because every model runs on real GPU time. If you only need a flat relief from a picture, our blog covers free extrusion workflows; when you want a true 3D mesh, that is what the generator does.
Is the STL watertight and ready to slice?
Models are generated as closed meshes and exported as binary STL, which every major slicer reads. Always preview in your slicer before a long print.
Can I also get GLB or OBJ instead of STL?
Yes. Every generation can be downloaded as GLB with full PBR textures, or converted to STL and OBJ in your browser at download time.

I filled my first map in just one afternoon! That's 24 props already.
