Our free and fast tool will convert your 3D MTL (OBJ Material File) model files to a standard FBX (Autodesk Filmbox) file that can then be edited further in most popular 3D editing packages or 3D printed without any further processing. Our conversion tool can also batch convert multiple MTL files; up to 200 files at a time can be converted.
To convert your MTL 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 MTL to FBX conversion process, see the conversion information section below.

An MTL (material) file is most commonly associated with the 3D model format OBJ and is used by the OBJ file format as a means to store material information related to the OBJ model. This material information may also include textures, which are typically stored in separate image files.
The information is stored within the MTL file as plain text, making it easy to read and modify by hand. An MTL file does not have much use without the accompanying OBJ file; however, it can be used with our range of MTL converters to convert the materials into other 3D formats that also support materials such as FBX.
Due to their nature in that they only store material data, FBX files, when imported, our tools will create some sample 3D geometry and apply the materials found within the FBX file to this geometry.

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.
If your original model file contains texture images and other texture-related data, these will be included in the final FBX file.
Many 3D file conversion websites use the same off-the-shelf components to convert files, these often lack features and full MTL file compatibility. Our bespoke file conversion tools offer full MTL file compatibility and have been developed in-house by a team of developers, some of whom have over 30 years of experience working with 3D graphics file formats, meaning our tools will convert your MTL file quickly and accurately with maximum compatibility.
Yes! Our MTL tool supports full batch conversions. You can upload up to 200 MTL 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.
First click the "Upload..." button, and select your MTL file to upload. You can also drag and drop your file onto the tool. Once your file is selected, you can set any configuration options. When the MTL to FBX conversion has completed, you can download your FBX file straight away.
We aim to process all MTL 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.
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.
Yes, of course! We do not store the MTL file you submit to us. The resulting FBX file, once created, is stored for 4 hours after upload; after this time it is deleted, and the short-term download link will stop working. You can create a long-term download Url with most tools that will ensure the file is retained for 24 hours, allowing you to download the file when convenient. Our tools also come with a Delete button, allowing you to delete the file immediately.
No. All our conversion tools process your MTL file on our dedicated conversion servers, meaning you can use our tools on low-spec computers, laptops, tablets, and mobile devices and receive your converted FBX file quickly.
Yes! Our MTL 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.
Yes. Although you can use an Ad Blocker, if you like our MTL conversion tool please consider white-listing our website. When an Ad Blocker is enabled there are some conversion limits and some settings may not be available when using our tools. Processing/conversion and download times will also be longer.
Yes. When you have converted your MTL to FBX, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.
