Convert Your 3D Mesh/Model MTL Files to OBJ

Our free and fast tool will convert your 3D MTL (OBJ Material File) model files to a standard OBJ (Wavefront) 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 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.

How to Convert your MTL to OBJ Online?

Here are two simple steps to convert your MTL to OBJ.

Upload a MTL File

Click the "Upload a MTL File" button and select a MTL to upload. The maximum file size is 100MB.

Download your OBJ File

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

Description

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.

MTL Notes

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.

Supported Features

  • Materials

Description

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.

OBJ Notes

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.

Supported Features

  • Mesh geometry
  • Materials (Via an MTL file)
  • Textures (PNG, JPG, TGA formats)

Frequently Asked Questions

Will the OBJ file retain the textures from my MTL 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.

How does ImageToStl.com differ from other MTL file conversion websites?

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.

I have several MTL files; can I batch convert my MTL to OBJ?

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 OBJ files individually or download them all in a single ZIP file.

How can I convert my MTL file to OBJ?

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 OBJ conversion has completed, you can download your OBJ file straight away.

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

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.

How accurate is the MTL to OBJ 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 MTL to OBJ on ImageToStl.com?

Yes, of course! We do not store the MTL file you submit to us. The resulting OBJ 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.

Do I need a high-spec. computer to use the MTL to OBJ converter?

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 OBJ file quickly.

Can I convert my MTL to OBJ on Windows, Linux, Android, iOS or Mac OS?

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.

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

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.

Can I get support with converting my MTL to OBJ?

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.
