Convert DAE to GLB

COLLADA to GLB, converted in your browser. DAE is the usual way models leave SketchUp, and GLB is the usual way they reach the web.

What breaks when you convert COLLADA to GLB

COLLADA is unusually well behaved about scale

Unlike most of the formats on this site, a DAE states its own unit scale and up axis in the file header, and we honour both. A file exported from SketchUp in inches and Z-up lands correctly sized and upright without you touching anything — which is a pleasant change from OBJ and STL, where the format simply has nowhere to record that information.

SketchUp’s double-sided faces lose their back materials

SketchUp gives every face a front and a back material, and its DAE export writes both. A glTF primitive has exactly one material, so the back material has nowhere to go. If your model relied on different colours per side — common in quick massing studies — the result will look wrong from inside.

Components are flattened into plain geometry

A SketchUp model made of repeated components stores the geometry once and places it many times. Flattening writes out every placement in full, so a façade with two hundred identical windows becomes two hundred separate copies of that window. Expect the file size and triangle count to grow accordingly.

Textures live next to the file, not inside it

A DAE references its images relatively, usually from a folder the exporter created beside it. Drop that folder’s contents alongside the .dae, or zip the whole export and drop that instead. Anything we cannot find gets named in the report.

Questions

Does this work with SketchUp exports?: Yes — DAE is SketchUp’s standard export format, and this is the most common reason people convert one. Export from SketchUp with textures, then drop the whole folder here.
Can you convert SKP files directly?: Not in the browser. SketchUp’s own format needs their SDK, which does not run as WebAssembly. Exporting to DAE from SketchUp first is the practical route.
Will my model come in upright?: It should. COLLADA records its up axis and we apply it, so a Z-up SketchUp export arrives Y-up and standing correctly for the web.
Why did my file get bigger?: Almost certainly component flattening. Repeated geometry that was stored once in SketchUp is written out once per placement in the GLB.
