About

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.

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.

Conversion trade-offs

KMZ: limitations to know

  • Essentially a ZIP archive, needs to be extracted for processing
  • Limitations of the internal KML format still apply

GeoJSON: what you gain

  • Human-readable, easy to manually edit and debug
  • Supported by virtually all GIS software and mapping libraries
  • Naturally suited for web applications and API data transmission

Why convert KMZ to GeoJSON?

Google Earth exports KMZ — a zipped KML with embedded icons and images. It is convenient to share but unreadable by web maps, GIS software, and data pipelines, which all want GeoJSON. Converting KMZ to GeoJSON unpacks the archive in your browser and turns its contents into clean features: placemarks, paths, and polygons with names and descriptions as properties, ready for Leaflet, Mapbox, or QGIS.

Frequently asked questions

What is the difference between KML and KMZ?

KMZ is the same KML compressed into a zip archive, sometimes with icons and images inside. This converter handles the unpacking for you.

Are embedded images extracted?

Geometry and attributes are converted; embedded overlay images are not part of GeoJSON and are skipped.

Are styles and colors preserved?

KML styling has no direct GeoJSON equivalent, but style names are kept as properties you can re-style from.

GeoJSON at a glance

Key Features

  • Based on standard JSON, natively supported by all programming languages
  • Supports multiple geometry types: Point, LineString, Polygon, MultiPolygon, etc.
  • Can carry attribute data and supports FeatureCollection for batch organizing features

Common Use Cases

  • Data exchange for web maps and online mapping services
  • Geospatial data storage and display in mobile applications
  • Sharing and transporting GIS data across platforms

How to Use

  1. 1

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