About

GeoJSON

GeoJSON is a geospatial data interchange format based on JSON. It can represent Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon, and GeometryCollection geometries. Defined by RFC 7946, GeoJSON has become one of the most popular data exchange formats in web GIS. GeoJSON files use WGS84 coordinates and support Feature objects with associated properties and FeatureCollections for organizing multiple features.

KMZ

KMZ is the compressed archive format of KML, packaging the .kml file and its associated images, icons, and other resources into a single ZIP archive. KMZ files are smaller and easier to distribute via email or web download. Google Earth can open KMZ files directly, automatically extracting and rendering the geographic content.

Conversion trade-offs

GeoJSON: limitations to know

  • Text format results in larger file sizes, not suitable for massive datasets
  • Does not support topology or spatial indexing

KMZ: what you gain

  • Single file containing all content, easy to distribute
  • Significantly smaller file size after compression

Why convert GeoJSON to KMZ?

When a dataset must be shared with people outside GIS, a KMZ is often the friendliest option: one small file that opens in the free Google Earth app on desktop and mobile, with every feature clickable and its attributes visible. Converting GeoJSON to KMZ compresses your data into exactly that — smaller than plain KML, self-contained, and instantly explorable by anyone.

Frequently asked questions

What is the difference between KML and KMZ output?

KMZ is the zipped version of the same KML — smaller to email and download. Content-wise they are identical.

Do attributes show in Google Earth?

Yes — every property is written into the feature description, visible in the popup when a feature is clicked.

Is there a file size limit?

No fixed limit; because processing is local, very large datasets are bounded only by your browser's memory.

How to Use

  1. 1

    Upload your GeoJSON file — drag and drop it onto the page, or browse from your device. You can add several files at once for batch conversion.

  2. 2

    The conversion runs automatically in your browser. No upload, no server — your data stays on your device the entire time.

  3. 3

    Download the KMZ file. Each input produces its own output, ready to use in your GIS, web map, or archive.
