What is a .LAZ file?
LAZ is a losslessly compressed LAS LiDAR point cloud.
- Did you know
- LAZ shrinks bulky LAS point clouds to a fraction of their size with no data loss.
- LAZ files are produced by LASzip, the open-source compressor written by lidar pioneer Martin Isenburg.
- LASzip can shrink a LAS file to roughly 7 to 20 per cent of its size while preserving every bit of the original data.
- What Analyser reads
- Header and metadata extraction for 3D meshes, voxels, BIM, point clouds and Gaussian splats: Wavefront OBJ, Stanford PLY, OFF, glTF, AMF, MagicaVoxel VOX, COLLADA DAE/ZAE, USD crate, X3D/VRML, LightWave LWO/LWS, Quake MD2/MD3/MDL, VRM avatars, Siemens JT, LAS/LAZ/PCD/PTS/E57 LiDAR clouds, IFC BIM, and .splat/.spz - vertex/face/point counts, bounding boxes, units and authoring tool.
- Depth of analysis
- .LAZ is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .LAZ file
- Drag a .LAZ file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
