COLLADA to USDA Converter
FileFlip converts COLLADA to USDA entirely inside your browser, using Assimp compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert a COLLADA file to USDA?#
- Drop your COLLADA file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to USDA and the conversion starts on its own. FileFlip downloads 11.2 MB of WebAssembly the first time and nothing after that, then runs Assimp on your own machine.
- Save the USDA file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting COLLADA to USDA lose quality?#
Not in the sense of pixels or samples. Converting COLLADA to USDA rebuilds the file in USDA's own model rather than re-encoding it, so everything USDA can represent comes through exactly and anything it cannot has to be dropped. Expect the geometry to be exact, and anything the target has no place for, such as a rig, to be left behind.
Is it safe to convert COLLADA files online?#
Yes, because nothing is uploaded. FileFlip converts COLLADA files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What COLLADA to USDA actually does to the file#
Converting COLLADA to USDA runs on Assimp, downloads 11.2 MB of WebAssembly the first time and nothing after that, rebuilds the file in the target's own model.
| Engine | Assimp |
|---|---|
| Conversion path | One step: COLLADA → USDA |
| Downloaded to your browser | 11.2 MB, once, then cached by your browser |
| Quality | Rebuilt in the target's model |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
What survives the conversion
| What is in the file | This conversion | Why |
|---|---|---|
| Materials | Sometimes | Survives for some files and not others. |
| Textures | Sometimes | Survives for some files and not others. |
| Skeleton and animation | Sometimes | Survives for some files and not others. |
What is a COLLADA file?#
A DAE file is an XML document in the COLLADA schema, created at Sony Computer Entertainment in 2004 and now maintained by the Khronos Group, describing a 3D scene's geometry, materials, lights, cameras and animation so it can move between authoring tools that don't share a native format.
Use COLLADA when a scene, not just a mesh, needs to move between two older authoring tools that both implement the schema.
Convert DAE to glTF for anything shipping to a web viewer, game engine or AR platform today, since that's the format those targets expect.
What is a USDA file?#
A USDA file holds a USD scene written out as plain UTF-8 text, spelling out every prim, attribute and layer composition line by line, in the encoding Universal Scene Description calls its ASCII form.
Use USDA while authoring or debugging a layer by hand, or whenever a file needs to go through text-based diff and review.
Convert USDA to USDC once a layer is finished and only needs to load fast, not be read by a person.
COLLADA to USDA questions people ask#
What is a DAE file?
A DAE file is a COLLADA document, an XML-based interchange format created at Sony Computer Entertainment in 2004 and now maintained by the Khronos Group. It describes a full 3D scene, geometry, materials, lights, cameras and animation, so it can move between authoring tools that don't share a native format.
What program opens DAE files?
Blender, SketchUp and Autodesk Maya all open DAE files, since COLLADA has long been supported as an import and export option across mainstream 3D and CAD tools. Which one to use depends on whether the goal is further editing or just viewing the scene.
Is COLLADA the same as glTF?
No, they're different formats with a shared lineage: both come from the Khronos Group, but COLLADA is a verbose XML schema for exchanging scenes between authoring tools, while glTF is a leaner JSON and binary format built specifically for efficient delivery to a renderer. glTF has largely replaced COLLADA for that delivery role.
Why do SketchUp exports come as DAE?
SketchUp has supported COLLADA export since early versions of the free edition, making DAE one of the standard ways to get a SketchUp model into another 3D application. It remains common in older pipelines and asset libraries built around that workflow.
