3MF to FBX
Convert 3MF to FBX online, free and without signing up. Drop in the 3MF file, set the units, scale and up axis, and save the FBX file. Nothing is uploaded: your browser reads and writes the model on your device.
How to convert 3MF to FBX
- 1Drop your 3MF file in, or click to choose it
- 2Check the units, the scale and the up axis
- 3Press Convert and save the FBX file
- A FBX file with your model, in the size you set.
What happens to your files
- Nothing is uploaded.Your 3MF file is read and the FBX file is written by your browser, on your own device.
- Checked after writing.The new file is read back, and anything that did not make it across is listed.
- Units and axes are yours.Set the units, a scale and the up axis before you save.
What you can do
- Convert 3MF to FBX with one tool: choose the units, a scale factor and the up axis (Z-up or Y-up) before you save.
- See the size the model will have in the new file, and a list of what the new format cannot hold, before you convert.
- Merge all parts into one mesh, or apply transforms so the positions are baked into the vertices.
- Look at the model in the preview first. Drop the companion files (.mtl, .bin, textures) or a ZIP together with it.
Good to know
- 3MF is a ZIP of XML files made for 3D printing. It stores the unit (millimetres here), several parts and colours, but this tool drops its textures.
- FBX is Autodesk's format for game engines and animation tools. It holds meshes, materials, bones and animations, and is written in centimetres here.
- STL, OBJ and PLY have no unit, so you choose one. 3MF is written in millimetres, FBX in centimetres and the other formats in metres.
- Not every format holds everything. STL keeps only the shape, PLY has no textures, and DAE leaves animations out. The page lists this before you save.
- A glTF or OBJ result is saved as a ZIP with the .bin or .mtl file and the textures next to the model.
- FBX, 3MF and DAE are written by a 7 MB add-on that loads once, from ToolRecipe itself, the first time you pick one of them.
Questions
Is 3MF to FBX free, and is my file uploaded?
It is free, and there is no sign-up. The file is not uploaded: your browser does the conversion on your device.
Does the model keep its size?
Yes, when the file states its unit, it is carried across. If it does not, you say which unit the numbers are in. The size in the new file is shown before you save.
Why is my model turned in the new file?
Some formats are Z-up (STL, 3MF) and others Y-up (GLB, USDZ, FBX). By default the model is turned to suit the pair. Change "Up axis" to keep it as it is.
What gets lost when I convert 3MF to FBX?
It depends on the two formats. The page lists what the new format cannot hold before you save, and checks the new file after writing.
