Convert KMZ files to Shapefile, online and free. GISConverter reads your KMZ data locally in the browser and writes a Shapefile file so you can load it into desktop GIS such as ArcGIS or QGIS — nothing is uploaded, and your data never leaves your computer.

KMZ is a vector GIS format, so it isn't always the format the next tool expects. Converting it to Shapefile lets you load it into desktop GIS such as ArcGIS or QGIS without redrawing or re-collecting anything. Because GISConverter runs a full GDAL engine in your browser, the geometry and attributes carry across faithfully, and the file never leaves your device.
KMZ (.kmz): A KMZ file is simply a KML document compressed into a ZIP archive, optionally bundling icons, images and overlays alongside it. It is smaller than raw KML and is the format Google Earth exports by default, which makes it the usual way to hand a finished map to someone else.
Shapefile (.shp): The Shapefile is the long-standing Esri vector format and remains the lingua franca of desktop GIS. A single “shapefile” is really a set of files that must travel together — at minimum .shp (geometry), .dbf (attributes) and .shx (index), usually with a .prj that records the coordinate system.
Yes. GISConverter is completely free and runs in your browser — no signup, no watermark, and no daily limit.
No. Your KMZ file is read and converted locally on your device with a GDAL engine compiled to WebAssembly, so it never leaves your computer.

A shapefile is really several files (.shp, .dbf, .shx, .prj) that must stay together, so GISConverter bundles them into a single .zip for download — and reads a zipped shapefile the same way on input.
Yes. Output defaults to EPSG:4326 (WGS84 longitude/latitude). Enter any EPSG code, such as EPSG:3857, in the coordinate-system box to reproject on the way out.
