Method · readable, no black box

What happens to your file, step by step.

DAE was the interchange format of the 2010s. This page turns one into an FBX of the rest-pose mesh, with node transforms applied and no materials invented.

1 · Parse the XML scene

Collada is XML: libraries of effects, geometries and nodes. The loader reads geometry and node transforms, not shaders.

2 · Flatten the nodes

Every mesh is baked into world space. Multiple geometries end up in one FBX scene.

3 · Write the FBX

The mesh is written with a single default material. No rig, no animation, no texture references.

Where the limits are

DAE → FBX data handling
Data	Behaviour	Why
Geometry	Kept	Triangulated, world transforms applied
Materials	Replaced	One neutral material
Animation	Dropped	Rest pose only
Units	Unchanged	Collada unit declaration ignored
Textures	Dropped	No image references

Check the scale first

Collada files are often authored in metres. If the FBX imports 1000 times too large, the unit mismatch is the cause, not the converter.

Checking the result yourself

Note the triangle count and bounding box the page shows.
Open the result in the program you will actually use and read its statistics.
Compare the dimensions with the source; a silent unit change shows up here first.
Look at the model from both sides: flipped normals are visible immediately.
