glTF is an open, JSON-based 3D transmission format that stores mesh geometry, PBR materials, textures, animation and scene hierarchy; the .gltf variant references external texture and binary files.

File Formats

File format information for STL and GLTF

Detailed information about the source and target file formats, including their capabilities and specifications.

STL Format

Extension:STL
Full Name:Stereolithography
Type:3D Model
Mime Type:model/stl
Format:Binary
Opens With:3D Printers, Slicing Software

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.

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.

GLTF Format

Extension:GLTF
Full Name:GL Transmission Format
Type:3D Model
Mime Type:model/gltf+json
Format:Binary
Opens With:Blender, MeshLab

glTF (GL Transmission Format): An open, JSON-based file format (.gltf) for efficient 3D model delivery. It supports geometry, materials, and animations, designed for web and cross-platform compatibility.

About the STL to GLTF converter

FurniMesh's STL to GLTF 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 GLTF 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).
