Open compressed LAZ point clouds online without another desktop viewer
What an online LAZ viewer should help you do
A good LAZ viewer should remove friction at the start of the workflow. Instead of decompressing data locally or passing large files between machines, teams can open the point cloud in a browser, inspect what matters, and decide whether to keep the job at review level or move straight into production outputs.
- Open compressed LAZ point clouds online in your browser
- Review RGB, elevation, intensity, or classification views
- Spot gaps, density issues, and obvious QA problems before deeper processing
- Share browser-based review with teammates or clients
- Move into terrain, contour, or vector deliverables when the dataset is ready
With Lidarvisor, that browser review does not have to stop at visualization. You can move from a quick first look into deliverables like DTM, DSM, contours, building footprints, tree outputs, wire lines, and pole locations inside the same workflow.
Why LAZ works so well for browser-based review
LAZ is the compressed version of LAS, which makes it a practical fit for browser-first workflows. Smaller files are easier to upload, store, and share between capture crews, consultants, and clients while keeping the same core LiDAR data available for review and downstream processing.
Typical LAZ viewer workflow in Lidarvisor
Upload the LAZ file and open it in the browser for a first review. Check coverage, elevation patterns, and classification views for obvious issues. Share the viewer when teammates or clients need to confirm the scene or project area. Generate the outputs you actually need, such as DTM, DSM, contours, slope maps, building footprints, tree outputs, wire lines, or pole locations. Export results in formats that fit the handoff, including TIFF, DXF, SHP, GeoJSON, or LAS.
If the job starts as a quick inspection but turns into deliverable work, you do not need to restart in a separate tool. That is the real advantage of pairing a browser LAZ viewer with processing and export workflows.

Frequently Asked Questions
A LAZ viewer opens compressed LAZ LiDAR point cloud files so you can inspect them visually before deeper processing or export work.
Yes. LAZ is the compressed version of LAS. The main advantage is smaller file size for storage, transfer, and browser-friendly review workflows.
Yes. A browser-based viewer is useful when project stakeholders need a fast visual review without installing desktop software first.
That depends on the project. Survey teams often move into terrain and contour deliverables, utility teams into vegetation or pole workflows, and forestry teams into canopy and tree analysis.
Summary
If you need to open LAZ files online, review them quickly, and keep the path to deliverables short, Lidarvisor gives you a browser-first workflow with no software to install.

Why LAZ viewer demand is rising in 2026
Browser LAZ review is no longer just a nice-to-have for desktop GIS teams. Survey, utility, forestry, and mobile mapping workflows increasingly pass around compressed LAZ files first because they are lighter to share, faster to open, and easier to review before anyone commits to terrain models, contour cleanup, or downstream CAD and GIS work.
Survey teams
Use a LAZ viewer online to spot coverage gaps, check strip alignment visually, and confirm that a contractor handoff is worth deeper processing.
Utility and corridor teams
Open compressed corridor data quickly to review poles, wires, and vegetation context before moving into extraction or repeat-inspection workflows.
Forestry and field crews
Share lighter LAZ datasets for browser-based review when handheld, SLAM, or drone capture teams need a fast checkpoint without mailing around huge LAS packages.
