STL Converter
Convert a STL file to other formats for free. No sign up or credit card required.
STL (Stereolithography): A file format (.stl) for 3D printing and CAD, representing surface geometry as a mesh of triangles. It's simple, widely supported, but lacks color or texture data. Or skip the conversion entirely — browse free STL 3D models ready to download.

STL Converter Capabilities
When converting 3D model or mesh files using our STL converter, we will attempt to convert color materials into a suitable format for use in the converted file.

About the STL converter
FurniMesh's STL converter runs entirely in your browser using a WebAssembly glTF/3D-mesh pipeline — your file never leaves your tab, and the conversion completes in seconds for typical furniture-model files. Materials, UV maps, and scene hierarchy are preserved wherever the target format supports them. There's no sign-up, no watermark, no per-file size cap enforced by the UI — practical limits depend on your browser's available memory.
FurniMesh natively outputs four formats — GLB, OBJ, SKP (SketchUp 2017+), and BLEND (Blender 3.0+). Bridge conversion via this converter additionally produces FBX, STL, GLTF, 3DM (Rhino), IFC, DAE, PLY, OFF, 3DS, and 3MF. Use the converter to bridge between any combination — or skip the conversion step entirely if you don't have a source file yet (the FurniMesh library ships every model in all four native formats pre-rendered).
