GLB is the single-file binary packaging of glTF, the "JPEG of 3D". One file carries geometry, materials, textures and animations, optimized for fast GPU loading. It is the standard for web 3D, AR on Android, e-commerce product viewers and real-time applications.
PLY was designed at Stanford for storing 3D-scanned data. Beyond plain geometry it can attach arbitrary per-vertex properties — most importantly vertex colors — which makes it the format of choice for 3D scans, photogrammetry output and point-cloud-derived meshes.
| GLB | PLY | |
|---|---|---|
| Geometry | GPU-ready triangle mesh | Triangle mesh / scan data |
| Units | Meters by spec | No |
| Colors & materials | Full PBR materials | Per-vertex colors |
| Animations | Yes | No |
| Typical use | Web, AR & real-time delivery | 3D scans & photogrammetry |
Yes — free with no accounts, no watermarks and no file-size limits. Conversion runs on your own machine, so there are no server costs behind it.
No. The converter runs entirely in your browser using WebAssembly. Your .glb file never leaves your device, which makes it safe for confidential designs.
Yes — parts and assembly hierarchy are preserved where PLY supports them, and you can optionally merge everything into a single mesh during conversion.
Yes. Every converted model opens in the built-in 3D viewer with an assembly tree, display modes and section views, so you can inspect the result first.
GLB can contain textures and animation, but this converter carries geometry, hierarchy and one flat base color per part; texture maps, rigs and animation tracks are omitted. The PLY result has no declared units and does not carry textures, animation or an assembly tree.
GLB is the binary form of glTF — the standard format for 3D on the web and in AR. What GLB files contain, how to open them free, and how to convert to and from GLB.
Most online CAD converters upload your intellectual property to unknown servers. Learn what actually happens to uploaded files and how client-side conversion avoids the risk.
