Our free and fast tool will convert most 3D mesh or MPD (Lego Model) model files to a standard WRL (Virtual Reality Modeling Language) 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 MPD files; up to 25 files at a time can be converted.
To convert your MPD file, click the Upload button above and select the file to convert. Once selected, the file will be converted to a WRL file and will be ready for download shortly afterwards. For more information about the MPD to WRL conversion process, see the conversion information section below.
First click the "Upload..." button, select your MPD file to upload. Select any configuration options. When the MPD to WRL conversion has completed, you can download your WRL file straight away.
We aim to process all MPD to WRL 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 MPD file you submit to us. The resulting WRL file, once created is deleted 15 minutes after upload and the download link will expire after this time.
Yes! Our MPD to WRL 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 MPD 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 MPD to WRL, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.
Yes! Our MPD tool supports full batch conversions. You can upload up to 25 and MPD files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the WRL files individually or download them all in a single ZIP file.

An LDRAW file, which uses the MPD file extension, is a 3D file format used to store Lego 3D models and is a popular open format used by enthusiasts to share their Lego creations.
Contained within an MPD file is information for each brick within the Lego object, as well as color and other relevant data. MPD files can be opened with the LDraw software.

The WRL file format is a 3D-based model format originally created in the 1990's that was aimed at website usage. The format is text-based and contains 3D geometry data such as vertices, faces, simple shapes, material information, and more.
This format, when launched, was hoped to become a standard 3D format; however, due to the large file sizes, it didn't see wide adoption, although it is a supported format within some CAD software applications. It was later superseded by the X3D file format, which shares most of the functionality of WRL files.
WRL files support material and color information. If your uploaded model contains color information, our tool will attempt to save this in the WRL file at the end of the conversion process. Texture information is not supported at this time.
Converting from the MPD file format to WRL 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 MPD file to a valid WRL 3D model. Let's start with the conversion process, which involves the following steps:
In its simplest form, an MPD file is a binary data file containing 3D data such as vertices, faces, normals, and more. When combined, these make up the 3D model you see on your screen.
For more information regarding the MPD file format, please see this great article that goes into a lot of detail explaining the MPD format.
With the MPD 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 WRL 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 WRL format.
