Format converter

3D Model Converter

Bring in a model you already have and write it back out in the format your engine, your slicer or your viewer expects.

01

Upload your model

GLB, glTF, FBX, OBJ or STL. It goes straight to your own private storage.

02

Pick the target format

FBX, OBJ, STL, glTF, USDZ or 3MF, with an optional pass to quad topology.

Conversion costs a fraction of a generation, and a failed job refunds itself.

Convert GLB to FBX for Unreal and Unity

GLB is what most AI generators and web viewers hand you, and FBX is what game engines and DCC tools import without argument. Upload the GLB, choose FBX, and download a file Unreal, Unity, Maya and 3ds Max all read. The trip back works too, so an FBX from your pipeline can become a GLB for the web.

Convert FBX to OBJ, and OBJ to FBX

OBJ is the format everything opens and nothing argues about, which is why it is still the safest handoff between two tools that disagree. Convert either direction without opening a modelling package, and keep the geometry you already paid to make.

Convert any mesh to STL for printing

Slicers want STL, and models arrive as GLB, OBJ or FBX. Upload whichever you have and get binary STL back. If you are starting from a picture rather than a model, the image to STL generator is the tool you want instead.

FAQ

Which formats can I upload?

GLB, glTF, FBX, OBJ and STL, up to the same size limit as the generator. Outputs are FBX, OBJ, STL, glTF, USDZ and 3MF.

Can you convert STL to STEP?

No. STEP, STP and other CAD formats describe solids rather than meshes, and converting between the two is a different job from the one this tool does. Everything here is mesh to mesh.

What does a conversion cost?

A few credits, well under the cost of generating a model. The exact figure for the options you picked is shown on the button before you press it, and a failed conversion returns its credits automatically.
