Accepts .glb files
Vertex Colors Preserved
GLB can store per-vertex color attributes. The converter extracts these and writes them into the PLY vertex color channels, keeping the original color distribution intact for visualization and analysis.
Convert Now
Research and Science Ready
PLY is the standard interchange format for academic 3D research, photogrammetry reconstruction outputs, and scientific visualization tools like MeshLab, CloudCompare, and Open3D.
Convert Now
Flexible ASCII or Binary Output
PLY supports both ASCII and binary encodings. The converter outputs binary PLY for compact file size while maintaining full compatibility with tools that read the PLY header to determine encoding.
Convert NowHow to Convert GLB to PLY
Upload Your GLB File
Drag and drop a GLB file into the upload zone or click to browse. Files up to 100 MB are supported.
Sign In and Convert
Sign in to start the conversion. The server extracts mesh data and vertex colors from the GLB and writes them into PLY format.
Download the PLY
Once ready, click Download and open the PLY in MeshLab, CloudCompare, Blender, or any PLY-compatible tool.

GLB and PLY: Different Tools for Different Pipelines
Why Use It
No Software to Install
The conversion runs entirely on the server. No MeshLab batch scripts, no local Python dependencies, no Blender add-ons required.
Vertex Color Support
Per-vertex RGBA color data embedded in GLB is extracted and written into PLY vertex color properties, preserving the visual appearance in color-aware tools.
Research Tool Compatible
PLY output is compatible with MeshLab, CloudCompare, Open3D, CGAL, PCL, and the majority of academic and scientific 3D processing pipelines.
Normals and UVs Included
Vertex normals and UV texture coordinates from the GLB are written as PLY properties, ensuring full geometry fidelity for downstream processing.

Frequently Asked Questions
Does the PLY output include vertex colors from the GLB?
Yes. If the GLB contains per-vertex color attributes, they are extracted and written into the PLY as red, green, blue, and alpha vertex properties.
Are textures included in the PLY output?
PLY does not support embedded texture images or UV-mapped materials in the way GLB does. UV coordinates are preserved as vertex properties, but texture image data is not embedded. If you need textures, consider converting to OBJ or GLB instead.
Can I open the PLY in MeshLab or CloudCompare?
Yes. Both MeshLab and CloudCompare natively import binary and ASCII PLY files. The converter outputs binary PLY, which both tools handle without any configuration.
What is the maximum GLB file size?
The converter supports GLB files up to 100 MB. High-polygon GLB files will produce correspondingly large PLY outputs.
Does the output include face normals or vertex normals?
Vertex normals from the GLB are written as nx, ny, nz properties in the PLY vertex element. Face normals are not written separately, which is standard practice for PLY mesh files.
