Laser-scanning software often exports scans as E57, while point-cloud tools and LiDAR workflows may require the smaller LAZ format. Converting lets you use the point data in LAZ-compatible software, but E57 scan metadata and attachments may not carry over.
What the E57 format is
E57 is a format for 3D imaging data, including point clouds from terrestrial laser scanners. Scanner software such as FARO SCENE and Leica Cyclone can create E57 files, and the format is commonly used to exchange scans between applications. An E57 file can include multiple scans, scan positions, color, intensity, and other data; the contents depend on the scanner and export settings.
What the LAZ format is
LAZ is the compressed form of LAS, a point-cloud format used in surveying, mapping, and LiDAR workflows. It stores point records such as coordinates and, when present, attributes like color and intensity. Compression makes files smaller than equivalent LAS files while retaining the point data, making LAZ useful for storage and transfer.
How to convert E57 to LAZ
Online on 101convert.com
- Upload the E57 file on the 101convert.com converter page. You can add several files for batch conversion; check the page for its per-file size limit.
- Select LAZ as the output format and start the conversion.
- Download the converted file or files when processing is complete.
Offline with desktop software
PDAL is a free, open-source command-line tool available on Windows, macOS, and Linux. Install a build that includes both the E57 reader and LAZ-capable LAS writer, then run:
pdal translate scan.e57 scan.laz --writers.las.compression=true
Replace scan.e57 and scan.laz with your filenames. If PDAL reports that the E57 driver is unavailable, use a build with E57 support enabled.
Global Mapper is a commercial desktop option that can open E57 point clouds and export LAS/LAZ. Open the file, then use File → Export → Export Vector/Lidar Format, choose LAS as the format, and enable LAZ compression in the export options. Menu labels and available export options can vary by version.
Quality and limitations
LAZ stores point records, not the full range of E57 content. Images, scan organization, scanner pose information, and other E57-specific metadata may be omitted or transformed during export. Check the output's point count and attributes in the target application, especially when converting files containing multiple scans or color and intensity data.
