Frequently Asked Questions

Common questions about LAS to CSV conversion

How does in-browser LAS 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 LAS files never leave your device memory, guaranteeing zero retention.

What is the main difference between LAS and CSV?

LAS (ASPRS LiDAR Point Cloud Exchange Format) provides airborne lidar surveys, gis elevation models, forestry canopy analysis, and urban scanning, 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 LAS 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.
