Frequently Asked Questions

Common questions about LAZ to CSV conversion

How does in-browser LAZ to CSV 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 CSV?

LAZ (LASzip Lossless Compressed LiDAR) provides high-efficiency lidar point cloud archiving, web-streaming gis, and bandwidth reduction, while CSV (Comma-Separated Values) is optimized for data science datasets, spreadsheet export, database dumps, and ml pipelines. Converting allows you to balance file size, compression fidelity, and platform compatibility.

Does converting LAZ to CSV 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.
