Convert KMZ files to GPX, online and free. GISConverter reads your KMZ data locally in the browser and writes a GPX file so you can load it onto a GPS device or fitness app — 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 GPX lets you load it onto a GPS device or fitness app 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.
GPX (.gpx): GPX is the open XML standard that GPS devices and fitness apps use to record waypoints, routes and tracks. Nearly every handheld GPS, running watch and mapping app can import or export it, which makes it the common language for outdoor and navigation data.
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.
