COLLADA is an XML-based scene format that predates glTF as the Khronos interchange standard. It can carry geometry, materials, animations and full scene hierarchies, and remains common in older game pipelines, Google Earth assets and DCC tool exchanges.
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.
| COLLADA | glTF | |
|---|---|---|
| Geometry | Polygon mesh scenes | GPU-ready triangle mesh |
| Units | Yes | Meters by spec |
| Colors & materials | Materials & textures | Full PBR materials |
| Animations | Yes | Yes |
| Typical use | Legacy game & simulation assets | Real-time engines & web pipelines |
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 .dae file never leaves your device, which makes it safe for confidential designs.
Yes — parts and assembly hierarchy are preserved where glTF 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.
COLLADA 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 glTF result contains the converted geometry, hierarchy and flat colors, but it cannot recreate texture maps or animation that were dropped on import.
