What is a .E57 file?
E57 stores laser-scan point clouds together with images and metadata.
- Did you know
- E57, standardised by ASTM in 2011, is a vendor-neutral format for 3D imaging data.
- E57 uses a hybrid design - an XML section describing the scan’s structure and sensors, plus binary blocks holding the dense point data.
- The ASTM E57 committee that drafted the format drew its members from scanner makers such as Leica, FARO and Trimble.
- 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
- .E57 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 .E57 file
- Drag a .E57 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.
