COLLADA is an XML-based scene format that predates glTF as the Khronos interchange standard. It can carry geometry, materials, animations and full scene hierarchies, and remains common in older game pipelines, Google Earth assets and DCC tool exchanges.
STL is the de-facto standard for 3D printing. It describes a model purely as a mesh of triangles — no color, no units, no assembly structure — which makes it simple, universally supported, and the required input for virtually every slicer, from PrusaSlicer and Cura to resin-printer tools.
| COLLADA | STL | |
|---|---|---|
| Geometry | Polygon mesh scenes | Triangle mesh |
| Units | Yes | No — unitless numbers |
| Colors & materials | Materials & textures | No |
| Animations | Yes | No |
| Typical use | Legacy game & simulation assets | 3D printing |
Yes — free with no accounts, no watermarks and no file-size limits. Conversion runs on your own machine, so there are no server costs behind it.
No. The converter runs entirely in your browser using WebAssembly. Your .dae file never leaves your device, which makes it safe for confidential designs.
Yes — parts and assembly hierarchy are preserved where STL supports them, and you can optionally merge everything into a single mesh during conversion.
Yes. Every converted model opens in the built-in 3D viewer with an assembly tree, display modes and section views, so you can inspect the result first.
COLLADA can contain textures and animation, but this converter carries geometry, hierarchy and one flat base color per part; texture maps, rigs and animation tracks are omitted. The STL result also has no units, colors, material data or part names, so keep the source alongside it.

Most online CAD converters upload your intellectual property to unknown servers. Learn what actually happens to uploaded files and how client-side conversion avoids the risk.
