6 Best Free GPX to KMZ Converter Software For Windows

Here is a list of best free GPX to KMZ converter software for Windows. GPX or GPS Exchange Format files carry common GPS data like routes, elevation, coordinates, waypoints, tracks, etc. Just like GPX, KMZ (Keyhole Markup Language Zipped) also carries similar GPS data set along with 3D models. In case you need to convert a GPX file to KMZ software, you can use any of the listed software. In many software, you can also convert GPX to unzipped file version i.e., KML.

Through most of these converters, you can also view GPX file route maps, waypoints, latitude, longitude, and more information over an interactive map. To fetch the interactive map, these software generally use Google Earth service. The interactive map allows you to closely analyze track points, waypoints, etc. Through some of these converters, you can also edit data of a GPX file before starting the conversion. To help you edit GPX before conversion to KMZ, these software offers tools like insert a new position, split track, connect track points, pan, etc. Plus, you can also add new information and mark new points over the map with ease.

Apart from GPX and KMZ, these software support many other file formats such as ASC, TRK, CSV, RTE, NMEA, GSB, SDAT, and more. Overall, all of these converters are feature rich and quite simple to use. Go through the list to know more about these software.

GpsPrune is a free open source GPX to KMZ converter software for Windows, Linux, Debian, and Ubuntu. This software is primarily used to view, edit, and convert the coordinate data of a GPX and other supported files namely TXT, KML, and KMZ.

To view the coordinate data, routes, waypoints, etc., of a GPX, it provides a viewing area with a map. However, in my testing, this software failed to fetch a map and to show the exact location of the recorded path information. Besides viewing the GPX file information, you can also edit it using its tools like connect track points, pan, create a new point, compress track, split the track into segments, etc. In this software, you can also get some additional features which can come in handy.
