Convert FBX to STL

Drop your FBX files and download them as STL — free, in batch, and they never leave your device.

FBX → STL: what you should know

FBX is Autodesk's interchange format for animation software and game engines. It's used mostly in gamedev (Unity, Unreal), skeletal animation (Mixamo), Autodesk pipelines, and it stores geometry, scene hierarchy, skeletons, animations and material references. STL, on the other hand, is the standard format of 3D printing: a triangle mesh with no explicit units, no color and no materials — the format expected by slicers (Cura, PrusaSlicer, Bambu Studio), FDM and resin 3D printing, CAD.

This tool converts your FBX files to STL right in the browser: no queue, no artificial size limit and, above all, your file is never uploaded to any server. Geometry is preserved with the exact coordinates and scale of the original — important if the model is going to be printed or measured.

Keep in mind: STL stores geometry only: materials, textures and colors are lost. If you need to keep that data, convert to a format that supports it (GLB keeps materials and textures; PLY keeps vertex colors).
