Convert LEGO Digital Designer models (LXF) online for free
The converter easily converts your LXF LEGO models to various formats - free and online. No LEGO Digital Designer or or other 3D software needed.
To convert other file formats to the "LEGO 3D Model File" file type, you need software like LEGO Digital Designer or a similar tool.
The .LXF file is a 3D model format originally developed by The LEGO Group for the LEGO Digital Designer (LDD) software. Internally, the file uses standard ZIP compression to bundle an XML-based LXFML document (which records the exact spatial coordinates, color codes, and part IDs of every brick) along with a PNG thumbnail image of the build.
The primary disadvantage of the .LXF format is that it relies on deprecated software. LEGO Digital Designer is officially discontinued, leaving users with legacy files that lack modern rendering capabilities and active developer support. Furthermore, .LXF is a highly proprietary, domain-specific format. Because it stores catalog part numbers rather than actual polygonal mesh data, you cannot natively open these files in standard 3D applications like Blender or Autodesk Maya.
To ensure your virtual LEGO builds remain accessible and useful, you must convert them. For continued editing within the modern LEGO fan community, convert .LXF to IO for BrickLink Studio or LDR for the open-source LDraw ecosystem. If your goal is external 3D rendering or game development, convert to OBJ or DAE (Collada). For 3D printing custom parts, you will need an STL conversion. Drag and drop your file here to analyze and convert it - free, online, and without installing software.
Use Convert.Guru to open and convert your LXF file.
Users also converted LXFML, PNG, LEF, IXF, IO, LFX, PDF, LDR, ZIP, LXXPLOT, TXT, JPG and LXL files.
If you want to convert LXF file to PDF, OBJ, FBX, DAE, 3DS, MAX, BLEND, MA, MB, C4D, STL or PLY, you can use LEGO Digital Designer or similar software from the "3D LEGO Model Storage" category. In the File menu, look for Save As… or Export….
To convert DWG, DAE, X3D, IGES, WRL, JT, SKP, 3DS, 3DM, OBJ, STEP or FBX files to LXF, try LEGO Digital Designer or another comparable tool in the "3D LEGO Model Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our LXF converter.
