Convert FBX to STL online

Drop a .fbx file to turn it into STL. You see the model in 3D before converting, and the file never leaves your device.

What is kept when converting FBX to STL

Geometry: Kept
Materials: Lost
Textures: Lost
Animation: Lost
Scene hierarchy: Lost

About FBX

Autodesk FBX

FBX is Autodesk’s interchange format used by Maya, 3ds Max, Blender, Unity and Unreal. It stores meshes, materials, skeletons and animation takes.

About STL

Stereolithography

STL describes only the surface of a model as triangles — no colors, materials or textures. It is the default format for 3D printing and slicers.

How it works

01
Drop the .fbx file (with its textures or .bin/.mtl files, if any).
02
Check the model in the 3D preview; STL is already selected.
03
Click “Convert” and the .stl file downloads.

Questions

Is the FBX to STL converter free?+

Yes, without limits, sign-up or watermark.

Is my FBX file uploaded?+

No. The FBX file is read and converted in your browser; nothing is sent to a server.

Why are textures missing after converting FBX?+

Textures stored as separate files must be selected together with the model. STL keeps them only if the format supports textures.
