PLY Converter

Inspect ASCII or binary PLY geometry and convert verified PLY pairs without changing model resolution.

Upload STL, PLY, or GLB directly. Use a ZIP for OBJ/MTL/textures or glTF resources. Direct self-contained OBJ and glTF files are also accepted. Limit: 1 GB.

What each format can retain

STL contains triangle geometry only. OBJ/MTL adds UVs, normals, simple materials, and external textures. PLY commonly stores geometry and vertex properties. glTF and GLB can retain modern scenes, PBR materials, skins, morph targets, and animation when the engine can represent them.

No repair or quality reduction claims

Conversion does not claim to repair a model, make it watertight, preserve CAD precision, or make it ready for 3D printing. Geometry is never decimated and textures are never resized to control server load.
