Convert Your 3D Mesh/Model X Files to FBX

Our free and fast tool will convert most 3D mesh or X (Direct X File) model files to a standard FBX (Autodesk Filmbox) file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing. Our conversion tool can also batch convert multiple X files; up to 25 files at a time can be converted.

To convert your X file, click the Upload button above and select the file to convert. Once selected, the file will be converted to a FBX file and will be ready for download shortly afterwards. For more information about the X to FBX conversion process, see the conversion information section below.

Click the download link once completed to receive your FBX file.

Frequently Asked Questions

How can I convert my X file to FBX?

First click the "Upload..." button, select your X file to upload. Select any configuration options. When the X to FBX conversion has completed, you can download your FBX file straight away.

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

We aim to process all X to FBX conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.

How accurate is the X to FBX conversion?

We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.

Is it safe to convert my X to FBX on ImageToStl.com?

Yes, of course! We do not store the X file you submit to us. The resulting FBX file, once created is deleted 15 minutes after upload and the download link will expire after this time.

Can I convert my X to FBX on Windows, Linux, Android, iOS or Mac OS?

Yes! Our X to FBX tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.

What if I am using an Ad Blocker, will that affect things?

Yes. Although you can use an Ad Blocker, if you like our X conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.

I have several X files; can I batch convert my X to FBX?

Yes! Our X tool supports full batch conversions. You can upload up to 25 and X files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the FBX files individually or download them all in a single ZIP file.

Description

The X 3D file format extension was introduced by Microsoft with the launch of Version 2 of their 3D graphics API, Direct X, back in 2002. The format has evolved over the years; however, in 2014, the X file format was deprecated in favor of newer, more capable formats such as FBX.

The format is a simple text-based file capable of storing 3D mesh information such as vertices, faces, normals, and material information. In addition to basic 3D information, the format can also store animations with the X file format, which is primarily used in the development of games.

X Notes

If your FBX file contains textures, these will be ignored. If a material contains color information, this will be translated where possible.

Description

The FBX format by AutoDesk was originally developed by Kaydara in the 1990s as a means to store 2D or 3D content with motion data. It has evolved over the years to become a widely used format by 3D modeling applications such as Blender, 3D Studio Max, and others due to its 3D animation capabilities.

The format is used to contain 3D models, which include vertices, faces, and other 3D geometry along with animation data. The format is proprietary; however, there is a publicly available API to use for development purposes. The file contents can be either text or binary, and work has been carried out by the Blender Foundation to document the format.

FBX Notes

If your original model file contains texture images and other texture-related data, these will be included in the final FBX file.

Supported Features

  • Mesh geometry
  • Materials
  • Textures

How does it work?

Converting from the X file format to FBX can be a complex process, and any tool used for this conversion process needs to be able to handle a variety of data conversion tasks as well as identify any defects within the 3D model and fix them. Here we will explain the conversion process used by our tool to accurately convert your X file to a valid FBX 3D model. Let's start with the conversion process, which involves the following steps:

Step 1: Read the Source X File

In its simplest form, an X file is a plain text file containing human-readable 3D data such as vertices, faces, normals, and more. When combined, these make up the 3D model you see on your screen.

When our tool reads this 3D data, all we are interested in are the vertices, faces, normals, materials, and textures, as this is the only data that can be accurately converted into the final FBX file.

The X file can contain data such as material definitions and textures that describe how a particular set of 3D geometry should be rendered. As we are creating an FBX file, which supports both materials and textures, our tool will attempt to load any materials and textures present in the X file.

For more information regarding the X file format, please see this great article that goes into a lot of detail explaining the X format.

Step 2: Process File Data

With the X file data read, our tool generates an internal representation of the full 3D model and will attempt to fix any geometry issues encountered. Along with repairing any issues with the 3D model, the tool will remove any duplicated vertices and prepare the model for exporting to the FBX format.

Step 3: Saving to the FBX Format

With the conversion process entering its final stages, our tool now needs to take the in-memory 3D model we have created in step 2 and convert it to the FBX format.

Along with the completed FBX file, any textures that were present in the original X file will be saved in either PNG or JPG format, depending on the original image format. If the original format was neither of these, for example, if your model contained a texture in the TGA format, it will be converted to a PNG.
