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.
OBJ is a plain-text mesh format from the world of computer graphics. It stores vertices, normals, texture coordinates and polygon faces, and nearly every 3D application — Blender, Maya, 3ds Max, game engines, renderers — can read and write it, making it a dependable lowest common denominator for mesh exchange.
| COLLADA | OBJ | |
|---|---|---|
| Geometry | Polygon mesh scenes | Polygon mesh |
| Units | Yes | No |
| Colors & materials | Materials & textures | Via MTL sidecar |
| Animations | Yes | No |
| Typical use | Legacy game & simulation assets | DCC tool interchange |
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 OBJ 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 OBJ result is a single geometry file with no generated MTL sidecar, so it does not carry textures or material definitions.
