Brilliant-cut sapphire in a gold prong setting — multi-material 3DS model with faceted geometry.
FBX is the current Autodesk interchange format, replacing the legacy 3DS format with full support for complex scenes, rigs, and animations.
FBX supports bone hierarchies, skinning weights, and blend shapes that the basic keyframe system in 3DS cannot represent.
FBX is the primary exchange format for Unity and Unreal Engine, and integrates directly with Maya, 3ds Max, and MotionBuilder.

How to Convert 3DS to FBX
Upgrade your legacy 3DS models to modern FBX for production pipelines.
Upload 3DS
Drag and drop or select your .3ds file. 3DS stores meshes and materials in an early Autodesk binary format.
Processing
Conversion runs entirely in your browser. Geometry and material data are extracted from 3DS and mapped to the FBX format. Your data never leaves your device.
Download FBX
Get your FBX file ready for import into Maya, 3ds Max, Unity, Unreal Engine, or any other FBX-compatible tool.
Why convert 3DS to FBX?
3DS was the original export format for Autodesk's 3D Studio on DOS, storing meshes, basic materials, and simple keyframe animations in a chunk-based binary container. Its hard cap of 65,536 vertices per mesh and single UV channel make it inadequate for modern production workflows. Many current tools treat 3DS as a legacy format with minimal ongoing support.
FBX replaced 3DS as Autodesk's primary interchange format. It supports polygon meshes with no vertex limit, PBR materials, skeletal rigs with skinning weights, blend shapes, multiple UV channels, and embedded textures. FBX is the standard interchange format in game development and film pipelines, with native support in Maya, 3ds Max, MotionBuilder, Unity, and Unreal Engine. Converting from 3DS to FBX brings legacy models into the current Autodesk ecosystem and modern production tools.
Key advantages of FBX over 3DS
FBX has no per-mesh polygon cap, removing the 3DS restriction.
FBX supports bone rigs and skinning weights for character animation.
FBX stores morph targets for facial animation and mesh deformation.
FBX supports several UV sets per mesh for lightmaps and detail maps.
FBX can bundle texture data inside the file for reliable delivery.
FBX is the primary import format for Unity and Unreal Engine.
