GPX to KMZ
Turn a GPX track into a KMZ, the zipped KML that Google Earth opens with a double-click and that is small enough to email.
Paste GeoJSON, KML, GPX, WKT or CSV
How it works
Add your GPX
Drop a GeoJSON, TopoJSON, KML or KMZ, GPX, CSV with coordinates, WKT, or a zipped shapefile, or paste the text. It is read in your browser.
Check the map
The features are drawn on a preview with their count, geometry types, bounds and attributes, so you can see it read correctly before converting.
Download the KMZ
Pick the output and download. Attributes come along; anything a format cannot hold is listed rather than dropped silently.
GPX to KMZ, ready for Google Earth
GPX to KMZ zips the converted KML so it is small enough to email and opens in Google Earth with a double-click. This GPX to KMZ converter keeps tracks, routes, waypoint names and elevation.
To convert GPX to KMZ, drop one GPX or several - several are merged into one KMZ with a folder each. GPX to KMZ online free, with nothing uploaded. Need the plain file? GPX to KML.

Why it matters
Attributes kept
Names, descriptions and every property travel with the features: KML ExtendedData, shapefile .dbf fields, CSV columns and GPX names.
Nothing uploaded
Survey data, client boundaries and GPS tracks stay on your computer. The conversion runs in this tab.
Coordinates untouched
Numbers are not reprojected or quietly shifted. Precision is yours to set: six decimal places is about 11 cm.
Questions
What is a GeoJSON file?
A GeoJSON file is JSON that describes map features: points, lines and polygons with their properties, in longitude and latitude on WGS84 (RFC 7946). Web maps such as Leaflet, Mapbox, OpenLayers and Google Maps read it directly.
Which formats can I convert?
In: GeoJSON, TopoJSON, KML, KMZ, GPX, CSV (lat/lon columns or a WKT column), WKT and zipped shapefiles. Out: GeoJSON, KML, KMZ, GPX, CSV, WKT, shapefile (ZIP), SVG and DXF.
Why does my shapefile need to be zipped?
A shapefile is several files: .shp holds the shapes, .dbf the attributes and .prj the coordinate system. Zip them together and drop the ZIP so the attributes and projection come too.
Does it reproject coordinates?
No. GeoJSON, KML and GPX all use longitude and latitude, so they convert exactly. A shapefile in UTM or a national grid keeps its numbers, and the page tells you so; reproject in QGIS or ogr2ogr if you need WGS84.
Can I convert several files at once?
Yes. Pick or drop several files together: they are merged into one output, and in KML each file gets its own folder. Tick "One file per upload" to get each converted separately in a ZIP instead.
Why is my GeoJSON in the wrong place on the map?
Usually longitude and latitude are swapped (GeoJSON is longitude first), or the data is in a projected system such as UTM. The preview and the bounds show which.
