Free online DAE to USD converter

Source format: DAE

DAE is a Collada 3D interchange file format, usually stored as .dae. It is used to exchange 3D models, scenes, meshes, materials, textures, and animation data between modeling and game-development tools. Common users include 3D artists, CAD and visualization workflows, and developers moving assets between applications such as Blender, Maya, 3ds Max, SketchUp, and game engines. DAE is useful when you need a broadly supported interchange format, but support quality can vary by application.

Target format: USD

USD stands for Universal Scene Description. It is a modern 3D scene format developed by Pixar and widely adopted in film, VFX, animation, and increasingly real-time pipelines. USD is designed for large scenes, layering, non-destructive editing, asset referencing, and collaboration. Typical USD-related file extensions include .usd, .usda for ASCII, .usdc for binary, and .usdz for packaged assets. Its main advantages are scalability, scene composition, and strong pipeline integration.

How to perform the conversion

The best conversion method depends on whether you need a simple geometry transfer or a production-ready scene export. For many users, Blender is the most practical desktop tool because it can import DAE and export USD.

1. Open Blender.
2. Import the Collada file with File → Import → Collada (.dae).
3. Check the imported model, materials, scale, and animation.
4. Export to USD with File → Export → Universal Scene Description (.usd/.usda/.usdc).
5. Choose the desired USD variant, such as .usda for readable text or .usdc for compact binary output.
6. Save the file.

If you prefer a command-line workflow, Blender can also be automated with scripts, which is useful for batch conversion. In many cases, the simplest option is to use the 101convert.com website, where you can convert the file for free without installing any software.

Notes on quality and limitations

DAE to USD is not always a perfect one-to-one conversion. Geometry usually transfers well, but materials, shaders, skeletal rigs, animation, cameras, and lights may not map exactly because the two formats use different scene models. Collada files can also contain application-specific data that USD may not preserve. If the source model uses complex textures or custom shaders, expect to do some cleanup after conversion. For best results, verify scale, orientation, animation playback, and texture paths in the target USD application. If your goal is archival or pipeline use, prefer .usda for inspection and debugging, or .usdc for smaller, faster-loading files.
