LAZ to OBJ Converter
Convert compressed LAZ point clouds into clean, triangulated OBJ meshes for smooth editing, high‑quality visualization, and 3D printing.
- Windows, macOS, Linux
Open and view LAZ files free. Building the mesh needs Points to Mesh, which requires a paid plan.
How to convert LAZ to OBJ

What to know about LAZ → OBJ
- LAZ is a LAS point cloud compressed without loss.
- OBJ is a text format; its materials and textures live in a separate .mtl file and image files.
- Turning points into a mesh needs Points to Mesh, which requires a paid plan; opening and viewing the points is free.
- OBJ stores no units, like STL.
Online or desktop
Online
In the web app, as in the desktop app, building a mesh from LAZ data needs Points to Mesh, which requires a paid plan. Exporting the finished mesh is free.
Desktop
The desktop app runs on Windows, macOS (Apple silicon) and Linux. Use it for large files, many files, and the tools the web app does not have. The free Community plan covers opening and exporting; see Pricing for what the paid plans add.
FAQ
Can I convert LAZ to OBJ for free?
Opening and viewing LAZ files is free on the Community plan. Building a mesh from them uses Points to Mesh, which requires a paid plan; exporting the finished mesh as .obj is free. The Pricing page lists what each plan includes, and the desktop app runs on Windows, macOS and Linux.
Do I need an account?
Yes. MeshInspector asks you to sign in, in the web app and in the desktop app. A free account opens and shows LAZ files; a paid plan unlocks Points to Mesh, the step that turns them into a mesh. You can see the plans on the Pricing page before you sign up.
Are colors and units kept?
OBJ stores no units, so check the size of the model after conversion. Colors and textures in OBJ live in a separate .mtl file and image files; the exported OBJ carries the mesh geometry, so check the result in your target app if you rely on materials or textures.
Which app should I use for large files?
Use the desktop app. The web app works within your browser's memory, up to about 4 GB, or 16 GB in browsers with 64-bit WebAssembly, while the desktop app uses the memory of your computer. It runs on Windows, macOS (Apple silicon) and Linux.
