How to convert OBJ to DAE
- Add your .OBJ file - drop it in the box above or click to browse.
- Convert it to .DAE in a few seconds.
- Download your new .DAE file.
What to expect
- Keep the
.mtlfile and texture images in the same folder as the.objbefore converting - without them the exported.daewill have no material data. - Complex PBR material properties (metalness, roughness maps) from extended
.mtlformats may not transfer fully; verify the result in your target application. - DAE (COLLADA) is XML-based, so
.daefiles are considerably larger on disk than equivalent binary formats like.glb- if file size matters, consider glTF/GLB instead.
Frequently asked questions
Does converting OBJ to DAE lose any geometry?
No - both formats store polygon meshes, so vertices, faces, normals, and UV coordinates transfer intact. Material data can be incomplete if the
.mtl file was missing at import time.Why does my exported DAE look grey or untextured?
OBJ materials are stored in a separate
.mtl file with linked texture images. Place the .obj, .mtl, and all textures in the same folder before importing, then re-export.Is COLLADA (.dae) still widely supported?
Yes - Blender, Unity, Unreal, and SketchUp all read DAE - but glTF/GLB is the more modern interchange choice. If your target application accepts both, glTF is generally preferable.
Can I batch-convert multiple OBJ files to DAE?
Yes - the
assimp command-line tool handles batch jobs via scripting, and Blender supports batch conversion through its Python scripting interface.Programs that convert OBJ: FBX Converter · AccuTrans 3D · Blender · PolyTrans|CAD+DCC · Autoconverter · modo · DAZ Studio · Bryce
