COLLADA files from SketchUp and older pipelines are large XML files that few modern viewers support. GLB is compact and opens everywhere. This converter runs entirely in your browser: the file is processed on your own device and never uploaded.
Why convert DAE to GLB?
COLLADA files from SketchUp and older pipelines are large XML files that few modern viewers support. GLB is compact and opens everywhere.
How it works
Drop your .dae file above and download the .glb. The conversion engine (Assimp, compiled to WebAssembly) runs inside the page, so it works the same on Windows, macOS, Linux and ChromeOS without installing anything.
DAE vs GLB
DAE (COLLADA): DAE is COLLADA, an XML interchange format maintained by the Khronos Group. It can hold scenes with meshes, materials, cameras, lights and animation. Used by: SketchUp exports, older game pipelines, and tools that predate glTF.
GLB (binary glTF): GLB is glTF packed into one binary file: scene description, geometry and textures together. That single self-contained file is why the web and AR use it. Used by: <model-viewer>, three.js, Android Scene Viewer, Shopify 3D product models, Blender and game engines.
Quality notes
Geometry, the node hierarchy and basic materials convert. A GLB is typically much smaller than the equivalent XML DAE. Textures referenced by external paths need to be available; otherwise the model keeps its colours without images.
Common use cases
Publishing a SketchUp model to the web; modernising an old COLLADA asset library; loading legacy scenes in three.js.
Frequently asked questions
Why convert DAE to GLB?＋
GLB is binary, much smaller, and supported by modern web and AR viewers; COLLADA support is fading.
Will my SketchUp colours stay?＋
Basic material colours convert. Check textures, which DAE references as separate image files.
Is the file uploaded?＋
No — it is converted on your device.
Does it keep the scene hierarchy?＋
Yes, nodes and transforms are preserved.
