Free Online LDRAW to OBJ Converter

You can use our MPD to OBJ conversion tool to quickly and easily convert your 3D model files for free. You may upload up to 20 files at one time, and our batch MPD to OBJ converter will process each 3D model and present you with a download link for each file once completed.

Select File(s)

Or drag and drop your files here to upload.
A maximum of 20 files can be uploaded at once.

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

Our 3D model MPD to OBJ tool will load your MPD 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.

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 MPD to OBJ work?

In order to successfully convert an MPD formatted file to the OBJ format, our converter tools will perform several initial checks to ensure the file provided is indeed an MPD file. There are many files out there where the file type extension does not match the data contained within the file. 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 MPD files to the exact specification.

Take your MPD file

An MPD file is a binary data file containing 3D data that makes up the 3D model, including vertices, faces, texture coordinates, and more. To guarantee efficient conversions, our tool will check all data that is contained within the MPD file and remove any information that is duplicated. This not only ensures the conversion completes more quickly, but also the generated OBJ file size is smaller.

Convert the data from MPD to OBJ

Now that the data from the MPD 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 OBJ file format. Part of this process ensures checking the capabilities of the OBJ format and removing any data that cannot be represented.

Save to the OBJ format

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

File format information for LDRAW and OBJ

Extension	MPD
Full Name	Lego Model
Type	3D Model
Mime Type	application/octet-stream
Format	Binary

The MPD file extension, which is also known as an LDRAW file, is a 3D graphics file format whose specialty is providing a format to store and display 3D Lego models.

With LDRAW-formatted files, complex Lego constructions can be defined using individual bricks. It is an open format with a large library of existing files that are freely available to download.

MPD files can be opened with the LDraw software, or you can use our range of MPD file converters to process MPD files into other formats.

LDRAW Converter Capabilities

When converting 3D model or mesh files using our MPD converter, we will attempt to convert colour materials into a suitable format for use in the converted file.

Extension	OBJ

Type	3D Model
Mime Type	text/plain
Format	Text
Opens With	MeshLab, CAD Assistant, DAZ Studio

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 colour, 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.

When converting your MPD to OBJ, our tool will attempt to accurately convert any colour or material information.

Information for converting from LDRAW to OBJ

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