Why Convert LAZ to OFF?
The short version: LAZ is optimized for aerial and terrestrial laser-scanning survey data, compressed for storage, OFF is optimized for geometry-processing research and academic mesh exchange, and this converter exists for the moment those two needs don't line up.
Our engine reads a file built around aerial and terrestrial laser-scanning survey data, compressed for storage and rebuilds it aiming to preserve this: a plain, easy-to-parse mesh structure — rather than producing a generic, lowest-common-denominator result.
LAZ is a compressed variant of the LAS LiDAR format, commonly used for aerial and terrestrial laser-scanning survey data, compressed for storage. That focus comes with a real limitation: a raw point cloud with no surface or mesh structure. OFF doesn't share that problem — its strength: a plain, easy-to-parse mesh structure.
How to Convert LAZ to OFF
- Upload your LAZ file.
- MiConvert converts it to OFF, aiming to preserve what makes OFF useful: a plain, easy-to-parse mesh structure.
- Download the converted OFF file.
- Use it directly with geometry-processing research tools.
Key Conversion Features
- Free for files up to 50MB, 100MB for registered accounts
- Built to handle the real-world quirks of files meant for aerial and terrestrial laser-scanning survey data, compressed for storage, not just a textbook version of the format
- Converts LAZ into OFF, aiming to preserve what matters most: a plain, easy-to-parse mesh structure
- Fast turnaround, typically under a minute per file
- Purpose-built for the shift from aerial and terrestrial laser-scanning survey data, compressed for storage to geometry-processing research and academic mesh exchange, not a generic pass-through

Frequently Asked Questions
What's the real difference between LAZ and OFF?
LAZ is built around aerial and terrestrial laser-scanning survey data, compressed for storage (a compressed variant of the LAS LiDAR format). OFF is built around geometry-processing research and academic mesh exchange instead (a simple research-origin polygon mesh format) — different enough that this is a genuine format conversion, not just a rename.
Is this conversion free?
Yes — free for files up to 50MB, with a 100MB limit for registered accounts, no subscription required.
Do I need surveying and geospatial software installed to convert my file?
No — the conversion happens entirely on our servers. You don't need surveying and geospatial software, and you don't need geometry-processing research tools either unless you plan to open or edit the OFF result afterward.
Why does OFF exist as a separate format instead of everyone just using LAZ?
Because they're built for different jobs — LAZ is aimed at aerial and terrestrial laser-scanning survey data, compressed for storage, while OFF is aimed at geometry-processing research and academic mesh exchange. Neither format is "better," they just fit different parts of a workflow.
Is the conversion from LAZ to OFF reliable?
Straightforward files convert reliably. LAZ's limitation — a raw point cloud with no surface or mesh structure — combined with OFF expecting geometry-processing research and academic mesh exchange, means unusual or edge-case source files can occasionally need a second look.
