KML Tools

KML (Keyhole Markup Language) is the XML-based format used by Google Earth, Google Maps, and many GPS and mapping apps. KMZ is the zipped variant that can also bundle images and 3D models.

This page lists every KML- and KMZ-aware tool on QuickMapTools: viewers, geometry operations, and converters to and from every common GIS format. Everything runs in your browser.

Frequently asked questions

What is the difference between KML and KMZ?

KMZ is a zipped KML, optionally bundling images, icons, and 3D models. Every QuickMapTools KML tool accepts both — drop a .kmz the same way you'd drop a .kml.

Does Google Earth still use KML?

Yes — KML is still the primary import/export format for Google Earth and Google Earth Pro.

How do I convert KML to Shapefile?

Use the KML to Shapefile converter. Drop the .kml or .kmz file, download a zipped Shapefile ready for ArcGIS or QGIS.

Why does my KML look fine in Google Earth but break in QGIS?

KML allows nested folders and stylesheets that some GIS tools mishandle. Convert to GeoJSON or Shapefile to flatten the structure for downstream GIS use.
