QUICK ANSWER
Is it possible to convert FBX to MAX?
No - not a direct conversion.

The only path from FBX to MAX is to import the .fbx inside a licensed copy of 3ds Max via File > Import and then save the scene with File > Save. Autodesk has never published the .max format specification, so no external tool can write it.

Why convert FBX to MAX?

A .max file is the native save format of Autodesk 3ds Max - an OLE2 compound-document container whose structure has never been publicly documented and changes between versions. FBX is a 3D interchange format designed for import into many applications. The only way to produce a .max file from FBX content is to import it inside 3ds Max and save; there is no converter path independent of the application itself.

How to convert FBX to MAX

3ds Max (3D Studio Max) APP

Open 3ds Max, use File > Import to bring in the .fbx and adjust scale and smoothing settings, then File > Save As to write the scene as a .max file.

PolyTrans|CAD+DCC APP

Use PolyTrans to convert the .fbx to OBJ, glTF, or another interchange format if a .max file is not strictly required.

Quality & what to watch

  • Autodesk has never published the .max format specification; writing a valid .max from outside 3ds Max is not practically possible.
  • If you only need to pass the asset to a 3ds Max user, send the .fbx directly - they can import it without needing a .max file.
  • For 3D interchange without 3ds Max, convert the .fbx to OBJ, glTF/GLB, or DAE using PolyTrans.

Frequently asked questions

Why can't a free converter produce a `.max` file?
The .max format is entirely proprietary and undocumented by Autodesk, and its structure changes between versions, making external writing impractical.
Do I really need to save as `.max` if I just want the model in 3ds Max?
No - a 3ds Max user can import the .fbx directly; a .max file is only needed to preserve 3ds Max-specific scene state such as modifiers and object properties.
Can I go the other direction - MAX to FBX?
Yes; open the .max in 3ds Max and use File > Export to write an FBX - that direction is a supported export path.
