What is kept and what is lost converting PLY to STL?
| Property | In PLY | In STL |
|---|---|---|
| Mesh geometry | Yes | Kept |
| Vertex colors | Yes | Dropped |
STL is a triangle-mesh format for 3D printing that stores only surface geometry — it has no concept of color, texture, materials or scene structure.

File format information for PLY and STL
Detailed information about the source and target file formats, including their capabilities and specifications.
PLY Format
PLY (Polygon File Format): An open file format (.ply) for 3D data, storing polygonal geometry and properties like color or texture. Developed by Stanford University, it’s flexible for scientific and 3D applications.
PLY Converter Capabilities
When converting 3D model or mesh files using our PLY converter, we will attempt to convert color materials into a suitable format for use in the converted file.
STL Format
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.

About the PLY to STL converter
FurniMesh's PLY to 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 STL format supports them (note: STL is a geometry-only format and discards materials by design). There's no sign-up (up to 20 conversions a day) and no watermark; files up to 50 MB — 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), PLY and OFF, and reads IFC, DAE, 3DS and 3MF files. Use the converter to bridge between supported formats — 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).
