Frequently Asked Questions

Common questions about LAZ to LAS conversion

How does in-browser LAZ to LAS conversion protect my privacy?

Unlike legacy file converters that upload your confidential files to cloud servers, OpenFileConverter runs 100% locally on your computer or phone using Rust WebAssembly. Your original LAZ files never leave your device memory, guaranteeing zero retention.

What is the main difference between LAZ and LAS?

LAZ (LASzip Lossless Compressed LiDAR) provides high-efficiency lidar point cloud archiving, web-streaming gis, and bandwidth reduction, while LAS (ASPRS LiDAR Point Cloud Exchange Format) is optimized for airborne lidar surveys, gis elevation models, forestry canopy analysis, and urban scanning. Converting allows you to balance file size, compression fidelity, and platform compatibility.

Does converting LAZ to LAS degrade visual quality?

No. OpenFileConverter uses high-fidelity chroma subsampling with configurable quality levels (default 92%), ensuring virtually indistinguishable image fidelity with sharp edges and rich colors.

Can I convert multiple files in batch?

Yes. You can drag and drop up to 100 files simultaneously. Because processing executes in parallel on your local CPU threads, batch jobs finish in seconds without queue wait times.
