How to convert COLLADA (DAE) to OBJ

DAE is open XML, but a full COLLADA reader is a large piece of software — scene graph, transforms, skinning, libraries — so this is a job for Blender rather than a browser tab. It is free and takes about a minute.

Why there is no uploader on this page

DAE is a closed format that no browser can read, so an in-page converter would have to send your file to a server. The procedure below does the job properly in the application that owns the format — and where a browser-side route exists, it is linked underneath.

Passo per passo

  1. 1Blender: File → Import → Collada (.dae), then File → Export → Wavefront (.obj).
  2. 2In the export panel, tick 'Triangulate Faces' if the target application dislikes n-gons, and choose whether to write the .mtl material file.
  3. 3If the model comes from SketchUp Free, apply object transforms after import (Object → Apply → All Transforms) so the OBJ is not offset from the origin.
  4. 4Check the up axis: COLLADA declares its own, and OBJ does not. Set Y-up or Z-up on export to match your target.
  5. 5Keep the .mtl and textures with the .obj when handing it over.

A cosa fare attenzione

  • Animation and skinning are lost — OBJ is a static geometry format.
  • Double-sided SketchUp faces often import with inconsistent normals; recalculate them in Blender before exporting.
  • MeshLab and Assimp's command-line tool are alternatives if you prefer not to open Blender.
DAE — COLLADA

The XML interchange format SketchUp Free and many older pipelines export. Verbose, widely supported, weak on solids.

OBJ — Wavefront OBJ

A plain-text mesh format listing vertices and faces — openly documented, which is why it can be read and rewritten in the browser.

Domande dei disegnatori

Can I do this without Blender?

Yes — MeshLab, Assimp (assimp export model.dae model.obj) and most 3D packages all read COLLADA.

Why is my model tiny or huge after conversion?

COLLADA stores a unit scale that OBJ cannot. Set the scale explicitly on export.
