Convert GLB to PLY
Convert a GLB file to PLY in your browser. Free, no upload, no sign-up.
Convert GLB files to PLY directly in your browser. The converter parses the GLB mesh, rebuilds it in memory and writes it out as PLY, keeping every triangle. Nothing is uploaded, there is no file size limit beyond your computer's memory, and the result downloads instantly. PLY preserves per-vertex colors from scans and is the native format of MeshLab and most scanning pipelines.
How to convert GLB to PLY
- 1Drop your GLB file
Drag a .glb file onto the box above or click to choose one.
- 2Check the preview
The model renders in 3D so you can confirm it loaded correctly. Dimensions, volume and triangle count are shown next to it; open edges are flagged if the mesh is not watertight.
- 3Download the PLY
Adjust the export options if needed and click download. Per-vertex colors are kept when the source has them; textures are not.
What is a GLB file?
GLB is the binary container for glTF 2.0, the "JPEG of 3D" maintained by the Khronos Group. A single .glb file bundles geometry, PBR materials, textures and animations, and is the standard format for 3D on the web and in AR viewers.
Commonly used by: web viewers (three.js, model-viewer), AR on iOS and Android, Sketchfab, game engines
What is a PLY file?
PLY was designed at Stanford to store 3D scanner output. It supports per-vertex colors and arbitrary custom properties, in either ASCII or binary encoding, which is why scanning and photogrammetry software prefers it over STL.
Commonly used by: 3D scanners, photogrammetry (Meshroom, RealityCapture), MeshLab, research tools
PLY preserves per-vertex colors from scans and is the native format of MeshLab and most scanning pipelines.
