GeoJSON to XZ Converter
Processing entirely on your device — large files may take a moment.
GeoJSON Geographic Data and XZ Compressed File exist for different jobs: GeoJSON is the web-standard format for maps: points, lines and polygons with properties, consumed by every mapping library. Unpack XZ into ZIP/TAR for tools that cannot read LZMA2.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the GeoJSON format
GeoJSON is the map format the web agreed on: a FeatureCollection of points, lines and polygons, each carrying arbitrary properties, in plain JSON. Leaflet, Mapbox, D3, QGIS and PostGIS all consume it directly, which is why almost every GIS workflow ends with “export as GeoJSON”.
Converting the older formats into GeoJSON (SHP, KML, GPX) is the bridge from institutional and device data into anything a browser can draw.
+Strengths
- ✓Consumed by every web mapping library
- ✓Plain JSON — easy to filter and edit
- ✓Properties travel with the geometry
!Limitations
- −Verbose for huge datasets
- −No built-in styling or symbology
About the XZ format
XZ wraps the LZMA2 algorithm: the best ratio of the common Unix compressors, which is why distribution packages and source releases pick it when bandwidth matters more than CPU.
Windows Explorer and many cross-platform tools cannot open it — unpacking to ZIP or TAR makes the payload portable.
+Strengths
- ✓Highest common ratio
- ✓Standard for Linux packages
- ✓Integrity checks built in
!Limitations
- −Memory-hungry at high settings
- −Sparse support outside Linux
Why convert GeoJSON to XZ?
Think of it as moving your file to the container that fits the job. Verbose for huge datasets XZ works differently: Highest common ratio If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this GeoJSON to XZ converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for GeoJSON to XZ?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Is there a size limit for archive conversion?
There is no upload cap because nothing is uploaded — the practical limit is your device memory. A few hundred megabytes of unpacked content works comfortably on a modern computer.
What about folders and directory structure?
The full directory tree is preserved: folders stay folders, and deep paths arrive exactly as they were packed in the GeoJSON file.
