Convert ICO to KMZ

Understanding ico and kmz file formats

ICO files are icon image files commonly used in Microsoft Windows to represent program, folder, or file icons. They can contain multiple images at different sizes and color depths. KMZ files, on the other hand, are compressed Keyhole Markup Language (KML) files used by Google Earth and other mapping applications to display geographic data, including placemarks, paths, and overlays. KMZ files can include images and other resources bundled together in a single ZIP-compressed file.

Why convert ico to kmz?

Converting an ICO file to a KMZ file is typically done to use a custom icon as a placemark or overlay in mapping applications like Google Earth. This process involves converting the icon image to a supported format (such as PNG), then embedding it within a KMZ file along with the necessary KML markup.

How to convert ico to kmz

1. Convert ICO to PNG: Use an image editor or converter to save your ICO file as a PNG image. Recommended tools include IrfanView (Windows) or XnConvert (cross-platform). In IrfanView, use File → Open to load your ICO, then File → Save As and select PNG.
2. Create a KML file: Write a KML file referencing your PNG image as an icon for a placemark. Example KML snippet:
   

   <Placemark>
     <name>Custom Icon</name>
     <Style>
       <IconStyle>
         <Icon>
           <href>icon.png</href>
         </Icon>
       </IconStyle>
     </Style>
     <Point>
       <coordinates>longitude,latitude,0</coordinates>
     </Point>
   </Placemark>

3. Bundle into a KMZ file: Place the KML file and the PNG image in the same folder. Select both, right-click, and choose Send to → Compressed (zipped) folder (Windows) or use a ZIP utility. Rename the resulting .zip file to .kmz.

Best software for ico to kmz conversion

• IrfanView – for converting ICO to PNG (Windows, free for non-commercial use)
• XnConvert – batch image conversion (Windows, macOS, Linux, free)

• 7-Zip or WinRAR – for creating ZIP/KMZ archives

Summary

While there is no direct one-step converter from ICO to KMZ, the process involves converting the icon to a PNG image, creating a KML file referencing the image, and packaging both into a KMZ archive. This allows you to use custom icons in mapping applications like Google Earth.
