glTF is the Khronos royalty-free standard for transmitting 3D scenes. The JSON variant keeps the scene description human-readable with geometry in sidecar buffers, and the ecosystem — Babylon.js, Unity, Unreal, Blender and the browser engines — treats it as the native interchange format for real-time 3D.
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.
| glTF | 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 | Real-time engines & web pipelines | 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 .gltf 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.
glTF 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.
