Free Online MAX to STL Converter

You can use our MAX to STL 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 MAX to STL converter will process each 3D model and present you with a download link for each file once completed.

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

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

Our 3D model MAX to STL tool will load your MAX 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.

File format information for MAX and STL

Full NameAutodesk 3ds Max
Type3D Model
Mime Typeapplication/octet-stream

A MAX file is the native (and proprietary) format of the 3D model editing software 3ds Max by Autodesk. 3ds Max is popular in a wide range of sectors, including video games, movies, professional animation, and amongst other 3D modeling enthusiasts.

The MAX file is the successor to the older 3DS format and was created to address the limitations of that format. A MAX file can contain 3D modeling data along with textures, animations, and scene lighting information, all within a single compact file format.

As already mentioned, the format is proprietary, and MAX files are designed to be opened and edited within the 3ds Max software only; however, it does provide options to export to formats such as FBX, which can then be converted to other formats using our FBX conversion tools.

MAX Converter Capabilities

Our MAX 3D Model/Mesh tool does not support any color material data contained within MAX files, so the converted file will not contain any color information.

Full NameStandard Triangle Language

Opens WithBlender, MeshLab, CAD Assistant, DAZ Studio

The STL, or Standard Triangle Language, file format has been around since the '80s and is supported by most modern 3D modeling applications. In particular, the STL format has become something of a standard format within the area of 3D printing, despite the rise of more modern formats such as 3MF.

STL files come in two flavors: binary or text format. The text format is human-readable, making it easy to perform manual edits, but can lead to very large file sizes. As you can imagine, the binary format is much more compact and represents the majority of the STL files you are likely to encounter.

The format itself is very simple; the 3D model is represented by a sequential list of triangles, with each triangle defined with 3 points consisting of their X, Y, and Z positions, along with an additional vector that contains the face normal (the direction the face is pointing). There is an additional attribute block for each triangle; however, this is largely unused and thus unsupported.

STL Converter Capabilities

Our 3D conversion tool does not support color or material information in STL files, so your file will not contain any color information.

Information for converting from MAX to STL

Your MAX file will be converted to a STL file using our unified 3D model and mesh conversion tool. Our MAX 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals, and relevant material information. Our tool will not attempt to transfer any color information if it is present in your MAX file; your final 3D model will contain only geometry data.
