How do I convert an FBX file to OBJ?

Drop the .fbx into the converter above; the .obj downloads seconds later. Both binary and ASCII FBX parse, and everything runs locally in your browser.

Do materials and textures come along?

No - the converter outputs the .obj mesh only, without an .mtl file. FBX materials often reference external texture files that are not in the file you drop anyway. UVs are preserved, so reassigning textures in Blender or your engine is straightforward.

What happens to the character rig?

OBJ cannot store rigs - the mesh exports statically in its rest pose. If you need the skeleton and animations, keep the FBX; OBJ is for when you need clean, portable geometry.

Why does my model import at a strange size?

FBX is commonly authored in centimeters and OBJ has no units - the numbers copy 1:1 and the receiving tool interprets them. If the model looks 100x too big or small, adjust the import scale in the target application.

Is my FBX uploaded anywhere?

No - parsing runs entirely in your browser. Game assets under NDA never touch a server here.

The FBX won't parse - what can I do?

Very old FBX versions (pre-2011 binary) occasionally fail in-browser. Re-export the file from any modern tool (Blender imports most FBX and exports fresh ones), or convert via GLB: import to Blender, export GLB, then use the GLB to OBJ converter.

How to convert fbx to obj

Drop your FBX file

Drag the .fbx file into the converter above or click to browse. No account and no upload - the file stays on your device.

Conversion runs in your browser

The model is parsed and rewritten locally, in seconds for typical files. Geometry is carried over 1:1 - no remeshing, no quality loss.

Download the OBJ

The .obj download starts from the same spot. Convert as many files as you like - there is no limit or watermark.

FBX and OBJ, explained

.fbx

What is FBX?

FBX is Autodesk's proprietary scene format and the long-standing standard for moving rigged, animated characters between DCC tools and game engines. Skeletons, skinning, blend shapes, and animation clips all travel inside one file.

Because the format is closed, no official browser tooling exists - this fleet writes FBX through assimp's open-source FBX writer running as WebAssembly, right in your browser. Static geometry with UVs is the reliable path; rigs and animation clips need a DCC-tool export.

.obj

What is OBJ?

OBJ is the plain-text workhorse of 3D interchange. It stores vertices, faces, UV coordinates, and normals in a human-readable file, with materials referenced from a companion .mtl file. Practically every 3D application of the last 30 years can read it.

Because OBJ splits materials and textures into separate files, a bare .obj carries geometry and UVs but shows up untextured unless the .mtl and texture images travel with it. It has no units, no rigging, and no animation - which keeps it simple and universally compatible.

Developed by: Wavefront Technologies (circa 1990)
Structure: Plain-text geometry, with materials in a separate .mtl file
Used by: Blender, Maya, 3ds Max, ZBrush, game engines, 3D scanners

What survives the fbx to obj conversion

Format conversion is honest work: some data has nowhere to go in the target format. Here is exactly what carries over.

Mesh geometry

All meshes are carried over exactly, with FBX scene transforms baked in - the OBJ matches the assembled scene.

UV coordinates & normals

Texture coordinates and normals survive, so downstream texturing and shading behave.

Rest pose

Rigged characters export in their bind/rest pose - the standard behavior for FBX-to-static conversions.

Materials & textures

The output is the .obj alone - no .mtl sidecar. FBX materials (and any external texture files) are not carried over.

Rig, skinning & animations

OBJ cannot store bones, weights, blend shapes, or clips. Keep the FBX if you need them.

When should you convert FBX to OBJ?

Convert to OBJ to free a mesh from Autodesk's closed format: sculpting apps, CAD tools, renderers, and scripts all read OBJ without an FBX SDK. It is also the safest archival format - plain text, no vendor.

Keep the FBX whenever rigging or animation matters - that is the format's entire reason to exist. Engines like Unity and Unreal also ingest FBX directly, so game pipelines rarely need this conversion.
