Convert KMZ to STL online

Drop a .kmz file to turn it into STL. You see the model in 3D before converting, and the file never leaves your device.

What is kept when converting KMZ to STL

Geometry: Kept
Materials: Lost
Textures: Lost
Animation: Not in KMZ
Scene hierarchy: Lost

About KMZ

Google Earth (KML + COLLADA)

KMZ is a zipped Google Earth package: a KML placemark with a COLLADA 3D model and its textures.

About STL

Stereolithography

STL describes only the surface of a model as triangles — no colors, materials or textures. It is the default format for 3D printing and slicers.

How it works

01
Drop the .kmz file (with its textures or .bin/.mtl files, if any).
02
Check the model in the 3D preview; STL is already selected.
03
Click “Convert” and the .stl file downloads.

Questions

Is the KMZ to STL converter free?+

Yes, without limits, sign-up or watermark.

Is my KMZ file uploaded?+

No. The KMZ file is read and converted in your browser; nothing is sent to a server.

Why are textures missing after converting KMZ?+

Textures stored as separate files must be selected together with the model. STL keeps them only if the format supports textures.
