Convert COLLADA to glTF
Convert COLLADA to glTF in your browser. The conversion runs on this page and the file never leaves your computer.
Result
Before you convert: what this keeps and what it destroys
Preserved
- The geometry, triangle for triangle
- Overall dimensions and proportions
- Watertightness, where the input is watertight
- Colour
- Separate parts and their positions
Destroyed
- A recorded unit: glTF stores none
Why people convert COLLADA to glTF
The same Khronos succession as the GLB route, in the readable JSON container, which makes it the one to pick when you want to compare input and output.
Both files are text. You can open the .dae and the .gltf side by side and see what became of a node, a material or a transform, which is genuinely useful when a scene comes through wrong and you need to work out at which end the problem lives.
The buffer is embedded as base64 so the result is one file. The declared unit scale is converted into metres and the up-axis is corrected on import.
What you get
You get a plain-text glTF file you can open in an editor containing the same triangles the COLLADA file described. No geometry is added, removed or approximated: mesh-to-mesh conversion is a change of container, and this site's tests check that the triangle count comes out identical.
The output uses metres, as required by the glTF specification.
Carried across: supported base or vertex colour, the supported part structure.
The conversion runs in your browser. Your file stays on your computer and is not uploaded.
What to check afterwards
- COLLADA declares its unit in the file. Check the output dimensions in the receiving application, especially when its import settings can override the unit.
If you need something this conversion cannot give you
This pair loses very little. glTF carries what COLLADA carries, so the main reason to choose a different target is what the receiving software accepts.
Going the other way
This site reads COLLADA but does not write it. For the reverse conversion, use an application that can export COLLADA.
How we know this conversion works
This pair was checked against 4 files from the test corpus on 2026-09-04. Each run parses its own output back in and compares the bounding box, the triangle count and, for closed solids, the volume against the input.
A pair that fails those checks doesn't get a page. That's why this site lists 120 conversions and not the several hundred a format-times-format grid would suggest.
