Browser-local workflow

How this tool works

  1. Step 1

    FBX

    Choose a FBX file from this device.

  2. Step 2

    Browser-local conversion

    The supported geometry is converted in this browser.

  3. Step 3

    OBJ

    Download the OBJ result when conversion is complete.

Direct answer

What is preserved when converting FBX to OBJ?

This converter processes the FBX file locally in your browser and downloads the converted OBJ file. Geometry is retained by the current loader and writer. Scene hierarchy uses a supported subset. Materials, textures, vertex colors, animation, and units and scale are not included in the downloaded file.

Before you convert

FBX to OBJ compatibility

These results describe Modelfy's current browser loader and exporter, not every feature allowed by the file specifications.

Data preserved, limited, or lost when converting FBX to OBJ
DataResultWhat this implementation does
GeometryPreservedGeometry is retained by the current FBX loader and OBJ writer.
MaterialsNot exportedThe exporter downloads one .obj file and does not create a companion .mtl file.
TexturesNot exportedThe exporter does not package or reference texture images.
Vertex colorsNot exportedOBJ output from this tool does not store vertex colors.
AnimationNot exportedOBJ output from this tool does not store animation.
Scene hierarchyLimitedMesh names are written, but parent-child transforms are baked into world-space vertices.
Units and scaleNot exportedThe FBX format can contain this data, but the current single-file loader does not retain it for conversion.

Verify after export

  • Confirm scale and units when opening the OBJ file in the destination application.
  • Compare material colors and textures with the browser preview before using the result in production.
  • Confirm that a static model is acceptable; animation is not exported.

Why choose this FBX to OBJ converter

Local FBX decoding

The selected FBX model file is decoded and rewritten as OBJ on your device; the model file is not uploaded to Modelfy.

FBX to OBJ data report

The compatibility table identifies geometry as preserved by this loader and writer.

OBJ output checks

Scene hierarchy is limited; review the implementation detail and verify the downloaded file in your destination tool.

Preview before export

Inspect the browser preview before converting, then use the post-export checklist to confirm the OBJ result.

How to convert FBX to OBJ online

  1. 01

    Upload your FBX file

    Drag and drop the file into the converter, or click Upload. FBX inputs up to 25 MB are processed locally.

  2. 02

    Convert to OBJ

    Preview the model in 3D, then click Convert. The conversion runs locally in the browser; processing time depends on model complexity and device resources.

  3. 03

    Download the OBJ file

    Your OBJ file downloads straight to your device, ready for the next tool in your pipeline.

About the FBX file format

Autodesk Filmbox

FBX carries complete scenes: meshes, materials, embedded textures, skeletons, and keyframe animation. It is the lingua franca between DCC tools like Maya, 3ds Max, and Blender and game engines like Unity and Unreal.

FBX is a proprietary format with binary and ASCII variants. Modern binary FBX (version 7.x, 2011 and newer) is what browsers can parse.

Format reference: Autodesk FBX documentation

Strengths

  • Full scene, rig, and animation support
  • Standard in game development pipelines
  • Embedded textures and materials

Commonly used for

  • Game engine asset import
  • Character animation exchange
  • DCC tool interoperability

About the OBJ file format

Wavefront OBJ

The Wavefront OBJ format has been a de facto interchange standard since the 1990s. It stores vertex positions, normals, texture coordinates, and faces in plain text, with materials described in a companion .mtl file.

OBJ does not support animation or scene hierarchies, which keeps it simple and portable across many modeling, printing, and rendering tools.

Format reference: Library of Congress OBJ format description

Strengths

  • Broad support across established 3D tools
  • Simple structure that is easy to debug
  • Reliable geometry interchange

Commonly used for

  • Static model exchange between tools
  • 3D printing preparation
  • Photogrammetry and scan output

Frequently asked questions

Is my FBX model file uploaded to a server?

The selected FBX model file is processed by the browser and is not uploaded to Modelfy. Website code and static assets still load over the network like a normal web page.

Will I lose quality converting FBX to OBJ?

Mesh geometry is preserved as closely as the OBJ format allows. The target format may triangulate geometry or drop unsupported features such as animations, materials, textures, or scene hierarchy.

Is the FBX to OBJ converter free to use?

Yes. The browser viewer, converter, and local 3D text tool require no account and add no watermark. Input limits vary by format, up to 50 MB; AI model generation is a separate credit-based product.

What is the maximum file size?

FBX inputs up to 25 MB are accepted. The format-specific limit keeps browser-local parsing bounded; actual processing also depends on available memory, model complexity, and device performance.

Why does my FBX file fail to load?

Browser parsing supports binary FBX 7.0 and newer (roughly 2011+). Very old FBX 6.x files and some ASCII exports are not supported — re-export the model from your 3D tool with a current FBX version.

Where are the materials and textures of my OBJ file?

OBJ stores materials in a separate .mtl file with texture images alongside it. This single-file browser tool does not request those companions, so it displays supported OBJ geometry with a neutral material; review the compatibility table before conversion.

AI 3D generation

From a single image to a production-ready 3D model

These browser tools stay free for viewing and converting files you already have. When the model does not exist yet, Modelfy generates a textured mesh from one reference image — the first one is free.
