Convert DAE (Collada) to OBJ

Collada (.dae) comes out of SketchUp, older game engines and many asset sites, while most tools import OBJ without trouble. Add the .dae together with its texture images and download an OBJ with an MTL material file and the textures. The file unit and up axis stored in the .dae are applied, so the model comes out upright at real size in metres. Nothing is uploaded.

How to use it

  1. 1

    Add the files

    Select the .dae together with its texture images, or just the .dae if it has none.

  2. 2

    Check the preview

    The model is shown with its materials and textures. Missing texture files are listed by name.

  3. 3

    Check the scale

    The unit from the .dae is already applied, so x1 is real size in metres. Change it only if the unit in the file was wrong.

  4. 4

    Download

    Get a ZIP with the OBJ, the MTL and the texture images, or the OBJ alone.

What to know before you convert

  • Animations and skeletons are dropped: OBJ only stores still meshes. A rigged model is written in the pose shown, and a note says so.
  • Cameras and lights in the .dae are left out.
  • Materials become OBJ materials with diffuse colour and the colour texture; shader effects are simplified.
  • Collada 1.4 and 1.5 are supported. Textures must be added with the .dae, since the file only names them.

Frequently Asked Questions

Add the .dae (and its texture images) on the box above, keep "ZIP: OBJ + MTL + textures" and click Download. Unzip it and import the OBJ.
Yes. SketchUp writes Collada with its textures in a folder next to the .dae. Add the .dae together with the images from that folder.
OBJ cannot store them, so they are dropped and the model is written as a still mesh. Use the DAE to GLB converter if you need to keep the animation.
The .dae says which unit it uses, and the converter applies it, so the OBJ is in metres. If the unit in the file was wrong, pick another scale before downloading.
No. The page reads the file and converts it inside your browser with the open-source three.js library. Nothing is sent to our servers, there is no account, and no credits are used. Closing the tab discards everything.
