Free Online KMZ to STL Converter

You can use our KMZ 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 KMZ 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 KMZ file, once uploaded to our server, will be deleted 15 minutes after upload, so please download your converted KMZ file before this time.

Our 3D model KMZ to STL tool will load your KMZ 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 KMZ and STL

Full NameKeyhole Markup Language
Type3D Model
Mime Typeapplication/

A KMZ, which is short for Keyhole Markup Zip, is a compressed ZIP file used to contain geographic files and data, including, but not limited to, 3D models, images, and terrain.

The 3D models that are included will use the popular DAE format, which is capable of storing animations, textures, and 3D geometry. Of course, the KMZ file uses the ZIP file format to compress all this data to reduce the final size.

KMZ files can be viewed using specialist software, or you can use our range of KMZ file converters to process KMZ files into other, more common formats.

KMZ Converter Capabilities

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

Full NameStandard Triangle Language
Type3D Model
Mime Typeapplication/
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 KMZ to STL

Your KMZ file will be converted to a STL file using our unified 3D model and mesh conversion tool. Our KMZ 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 KMZ file; your final 3D model will contain only geometry data.
