mapverter

SHP to KMZ Converter

Convert a Shapefile to a compressed KMZ in your browser. The .prj is used to reproject to WGS 84, and each Shapefile in a ZIP gets its own folder.

A KMZ is a zipped KML

The KMZ that mapverter writes is a ZIP archive containing a single compressed doc.kml. Inside is exactly what a KML download would hold: placemarks in WGS 84, a placemark name taken from the name field, and every other field as ExtendedData.

Reprojected from the .prj

KMZ, like KML, only uses WGS 84, so the target coordinate system is locked. mapverter matches the .prj by EPSG code or by its projection parameters, falls back to the .prj definition itself when the system is not in its list, and converts every coordinate. If there is no .prj, coordinates within longitude and latitude ranges are treated as WGS 84. Otherwise you choose the source system from the offered candidates, by clicking your area on the map to try the local UTM zone, or by searching for an EPSG code or name.

What to expect inside

  • A ZIP with several Shapefiles becomes one KMZ with a folder for each Shapefile.
  • Shapefiles have no colors or symbols, so the placemarks are written without styles.
  • Features without geometry are left out and counted in the conversion report.

Frequently asked questions

Should I choose KMZ or KML?
They contain the same placemarks. KMZ is compressed into a ZIP, so the file is usually smaller; choose KML if the receiving app needs a plain-text file.
Does the KMZ include images or icons?
No. It contains only doc.kml, and a Shapefile has no styling to carry over.
Can I keep projected coordinates in a KMZ?
No. KMZ always uses WGS 84 longitude and latitude. Download SHP or CSV if you need projected coordinates.
Are my files uploaded?
No. The conversion runs in your browser, and the Shapefile never leaves your computer.
