Step-by-step tutorials
Guides for Ouster PCAP, ROS 2 MCAP, E57, LiDAR inspection, and point-cloud conversion.
Start with the converter overview →Convert a supported PCD point cloud to compressed LAZ locally in your browser. Check the preview and attribute warnings, then download the full-resolution result without uploading the source file.
Read article →Prepare XYZ, headed CSV, or PTS point data, preview it in 3D, and convert to LAZ locally with the Klar3D Point Cloud Converter.
Read article →Convert a supported LAZ point cloud to binary PCD locally, preview the source, and check attributes and metadata before downloading.
Read article →Extract one frame or a range from an Ouster PCAP and download LAZ, PCD, or a ZIP of point clouds locally in your browser.
Read article →Convert multiple PCD, PLY, LAS, LAZ, XYZ, CSV, or PTS files locally, with a serial queue and folder output where your browser supports it.
Read article →Convert a supported ROS 2 MCAP PointCloud2 recording to LAZ or PCD in your browser, then download the result as a file or ZIP without uploading the recording.
Read article →Select scans from an E57 file, inspect their point counts and bounds, and convert to LAZ or PCD locally with Klar3D's browser prototype.
Read article →Open an Ouster PCAP with its sensor JSON, inspect missing columns and incomplete frames, and preview LiDAR recordings locally with Klar3D.
Read article →Open LAS, LAZ, COPC, PLY, or PCD LiDAR data in your browser, check file details and point attributes, measure and crop useful areas, and verify a dataset before installing CloudCompare.
Read article →Open a supported ROS 2 MCAP PointCloud2 recording in WolkeViz, select a LiDAR topic, inspect frames, measure or clip data, and export PCD samples locally—without installing software, logging in, creating an account, or uploading the recording.
Read article →A step-by-step guide to opening an indexed ROS 2 MCAP PointCloud2 recording and exporting one or many LiDAR frames as local PCD files—without an account, upload, or conversion software.
