KMZ is simply a KML file (plus any referenced icons or overlays) compressed into a single ZIP archive with a .kmz extension. It's the format Google Earth produces when you save a place, because bundling everything into one compact file makes maps easy to email and share. Under the hood it's still KML, so a KMZ converts cleanly to and from every other geographic format.
Need the other direction instead? GeoJSON is the open standard for encoding geographic data in JSON. GeoJSON is an open standard (RFC 7946) for representing geographic features — points, lines and polygons — together with their attributes as plain JSON. It's the lingua franca of modern web mapping: readable by virtually every GIS tool, library (Leaflet, Mapbox GL, OpenLayers, deck.gl) and programming language out of the box. Its simplicity and human-readability make it the natural hub format to convert to and from.

KMZ to GeoJSON — FAQ
- How do I convert KMZ to GeoJSON?
- Upload your .kmz file using the converter above (drag & drop or click to browse). GeoMaps converts it to GeoJSON instantly in your browser and gives you a .geojson file to download. No software to install and no signup required.
- Is the KMZ to GeoJSON converter free?
- Yes — it's completely free with no usage limits, watermarks or account needed. We offer it as a free tool from GeoMaps, the platform for turning your data into interactive maps.
- Is my data private? Are my files uploaded to a server?
- No. The conversion runs entirely in your web browser using JavaScript — your file is never uploaded to any server. Because nothing leaves your device, it's safe for sensitive or confidential data and works even offline once the page has loaded.
- Can I convert GeoJSON back to KMZ?
- Yes. Use our GeoJSON to KMZ converter for the reverse conversion — every format on GeoMaps converts both ways.
- How large a file can I convert?
- Because conversion happens in your browser, the limit is your device's memory rather than a server quota — files up to tens of megabytes convert comfortably on a typical laptop. Very large datasets may be slower depending on your machine.
