Convert GPX files to KMZ, online and free. GISConverter reads your GPX data locally in the browser and writes a KMZ file so you can share it as a single, compact Google Earth file — nothing is uploaded, and your data never leaves your computer.

GPX comes from GPS devices and outdoor apps, so it isn't always the format the next tool expects. Converting it to KMZ lets you share it as a single, compact Google Earth file 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.
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.
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.
Yes. GISConverter is completely free and runs in your browser — no signup, no watermark, and no daily limit.
No. Your GPX file is read and converted locally on your device with a GDAL engine compiled to WebAssembly, so it never leaves your computer.
