Our free and fast tool will convert most 3D mesh or MTL (OBJ Material File) model files to a standard OBJ (Wavefront) 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 MTL files; up to 25 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 OBJ file and will be ready for download shortly afterwards. For more information about the MTL to OBJ 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, OBJ files, when imported, our tools will create some sample 3D geometry and apply the materials found within the OBJ file to this geometry.

The OBJ file format, originally created by Wavefront Technologies and later adopted by many other 3D software vendors, is a simple text-based file format for describing 3D models/geometry. This data can include vertices, faces, normals, texture coordinates, and references to external texture files.
As the format is text-based, it is relatively straightforward to parse in 3D modeling applications. A downside of the text-based format is that the files can be rather large compared to similar binary formats such as STL and compressed files such as 3MF.
Our tool will save any material and texture files separately; these additional files will be included with your final OBJ file at the time of download.
First click the "Upload..." button, select your MTL file to upload. Select any configuration options. When the MTL to OBJ conversion has completed, you can download your OBJ file straight away.
We aim to process all MTL to OBJ 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 OBJ file, once created is deleted 15 minutes after upload and the download link will expire after this time.
Yes! Our MTL to OBJ 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 site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.
Yes. When you have converted your MTL to OBJ, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.
Yes! If your MTL file contains textured geometry, the texture image files along with the texture coordinates (UV data) will be exported with the final OBJ file.
Yes! Our MTL tool supports full batch conversions. You can upload up to 25 and MTL files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the OBJ files individually or download them all in a single ZIP file.
