A maximum of 20 files can be uploaded at once.

Please note: Your OBJ file, once uploaded to our server, will be deleted 15 minutes after upload, so please download your converted OBJ file before this time.

Our 3D model OBJ to FBX tool will load your OBJ file and, where supported, attempt to extract all the relevant 3D features, such as geometry, textures, and animations. To access the 3D conversion configuration options, click the button when you have selected your files. The current options support the ability to voxelize your 3D model and more.

How long does it take to convert my OBJ to FBX?

We aim to process all OBJ to FBX conversions as quickly as possible; this usually takes around 5 seconds; however, this can be longer for certain files, so please be patient.

How accurate is the OBJ to FBX conversion?

We aim to provide the best conversion experience. Our tools are under constant review and development, with new features being added every week.

How does converting OBJ to FBX work?

In order to successfully convert an OBJ formatted file to the FBX format, our converter tools will perform several initial checks to ensure the file provided is indeed an OBJ file. There are many files out there where the file type extension does not match the data contained within the file. To make things more difficult when working with OBJ files is the fact the OBJ file extension is used for other file formats such as the X-Plane format.

Along with these file type checks, our tools will do additional checks to ensure the file is correctly formatted to match the provided file type. There are many tools out there that do not always create OBJ files to the exact specification.

Take your OBJ file

The Wavefront OBJ file format is a text-based format, meaning its contents are human-readable, making smaller OBJ files easy to edit in simple text editors. Larger 3D models quickly generate large text files making hand-editing them in a text editor unwise. Within this text-based format are the core elements that make up the 3D model, including vertices, faces texture coordinates. To ensure efficient conversions, our tool will check all data that is contained within the OBJ file and remove any information that is duplicated. This not only ensures the conversion completes more quickly, but also the generated FBX file size is smaller.

Along with the core data that makes up the 3D model, our tool will check the OBJ file for the presence of texture coordinates to ensure any texture-based materials are converted correctly. Even if the texture files are not presented with the OBJ file, our converter will preserve any texture coordinates when converting to the FBX format.

Convert the data from OBJ to FBX

Now that the data from the OBJ file has been processed, our tool can apply any conversion specified options, such as enabling Voxel mode, and with these applied, prepare the data to be converted to the final FBX file format. Part of this process ensures checking the capabilities of the FBX format and removing any data that cannot be represented.

Save to the FBX format

At this point, the OBJ to FBX conversion tool will have the 3D model in a state that is ready to be transferred to the FBX format. Our tool creates the FBX file, ensuring all the model data is present and is formatted to match the FBX file specification to ensure the file opens in compatible FBX file editors.

If the OBJ file contains texture images, these will be exported to a format that is compatible with the FBX format. For most textures that are stored as JPG or PNG images, these are transferred with no changes. However, if there are other formats, such as TGA, these will be converted to a suitable format.

If an OBJ texture does need to be converted to a different image file format, our tool will ensure the quality and resolution are not degraded during the conversion process.

The OBJ file format is a 3D graphics file format used to define complex 3D models, including geometry, materials, and textures. OBJ files are text files, making them human-readable and easy to modify by hand. The downside to this ease of readability is that the files can become rather large when dealing with large or complex 3D models.

As mentioned, the OBJ format stores not only 3D model geometry but also materials and textures. These materials are usually defined in a separate file with the MTL file extension and specify geometry rendering details such as diffuse and specular color, transparency, and much more.

The OBJ material file can also reference external texture files. These are usually JPEG or PNG files; however, these can be older formats, such as TGA. Where materials are used, the OBJ file will also contain material names preceding the geometry faces they should be applied to. If textures are referenced, the geometry will also contain texture coordinates (UV) for each vertex.

FBX files are an open 3D file format developed by Autodesk for use with their Maya and 3Ds Max applications. An FBX file may contain any number of 3D objects, their associated geometry, materials, textures, animations, and more, all within a single convenient package.

The content of an FBX file is a mix of binary and ASCII text, producing a format that is both human-readable and compact. Due to their compact size, ease of use, and widespread support, FBX files are a popular choice for creating 3D animations and are also a staple in the videogame development scene.

The development of the FBX format continues to this day, with new features being included in each release. Along with being used within Autodesk's own editing solutions, FBX files can also be opened and edited in other popular 3D modeling applications, such as Blender.

Information for converting from OBJ to FBX

Your OBJ file will be converted to a FBX file using our unified 3D model and mesh conversion tool. Our OBJ 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals, and relevant material information. As both OBJ and FBX support color material information, our tool will also attempt to convert the color information.
