KMZ Viewer
Open KMZ files on a large interactive map. Explore placemarks, routes and boundaries, inspect attributes, and export your geographic data.
Map & satellitePoints, lines & polygonsFolders & stylesLocal file processing20 MB per archive • Up to 10 extracted KML documents • 100,000 coordinates / 5,000 geometry parts per session.
Archive contents are extracted in your browser. Each contained KML is loaded as a separate document, with doc.kml first. External map providers receive your IP address and requested map areas. Remote KML links and images are not fetched.
Statistics reflect visible geometry parts. Length and polygon area are spherical estimates, not surveying measurements. Polygon holes are subtracted; overlapping polygons are counted separately. Altitudes are preserved as supplied; the map is a 2D view.
Files & folders
Toggle folders or individual features. Turn off “KML styles” to use each file’s color.

Search filters the table only. Use the checkboxes to change the map and exports.

Exports include visible geometry parts. KMZ export contains one generated doc.kml and does not include original bundled assets. KML export preserves names, plain-text descriptions, folders, basic styles, altitude modes and attributes. MultiGeometry is split into separate placemarks; gx:Track becomes a line. Tours, overlays, models, time animation and vendor extensions are not preserved. PNG contains geometry only, without background imagery.
Supported KMZ content and limits
Supported: Point, LineString, Polygon with inner holes, MultiGeometry, Folder, Document, local Style / normal StyleMap, ExtendedData, and gx:Track / gx:MultiTrack as lines. Original visibility flags are applied when loading.
NetworkLink, GroundOverlay, ScreenOverlay, PhotoOverlay, Model, Tour, external style files and external icons are not rendered. Unsupported elements are reported after import. Self-intersecting polygons and areas spanning more than a hemisphere can give unreliable area results. Plain KML and GeoJSON imports belong in their separate viewers. Bundled images and icons are not rendered. Password-protected, split and ZIP64 archives are unsupported. Extraction limits: 1,000 archive entries, 100 MB declared uncompressed size, 10 MB per KML document and 40 MB combined KML content.
KMZ Viewer – View KMZ Files Online
A KMZ Viewer is a simple online tool that lets you open and view KMZ files directly in your browser. You do not need to install any special software.
KMZ files are commonly used with Google Earth, maps, GPS data, and geographic information. A KMZ file can contain locations, routes, boundaries, markers, and other map information.
What is a KMZ File?
KMZ is a compressed version of KML (Keyhole Markup Language). It can store geographic information such as:
- Locations and place markers
- GPS routes and tracks
- Areas and boundaries
- Lines and paths
- Map descriptions
- Images and other supporting files
How to Use the KMZ Viewer
Using the KMZ Viewer is easy:
- Open the KMZ Viewer.
- Upload your KMZ file.
- The tool reads the file and displays the data on an interactive map.
- Zoom in or out to explore the map.
- Click markers, lines, or areas to view available information.
Why Use an Online KMZ Viewer?
An online viewer is useful when you want to quickly check a KMZ file without installing Google Earth or other mapping software.
It can be helpful for:
- GPS and mapping work
- Survey and field data
- Travel routes
- Geographic projects
- Network and telecom planning
- Property boundaries
- Location analysis
- Checking KML/KMZ files before sharing them
KMZ Viewer Features
Depending on the tool, you can view your KMZ data on an interactive map and inspect locations, routes, paths, and boundaries. Some viewers may also provide information such as coordinates, distance, elevation, or other geographic details.
KMZ vs KML
KML is normally an XML-based geographic data file, while KMZ is a compressed package that can contain a KML file and related resources.
KMZ = Compressed KML + supporting files
FAQ on KMZ Viewer
Yes. You can upload a KMZ file to an online KMZ Viewer and view its geographic data on a map.
No. An online KMZ Viewer can let you view the file directly in your web browser.
A KMZ file can contain locations, routes, paths, boundaries, descriptions, images, and other geographic information.
KML is an uncompressed geographic data file, while KMZ is a compressed package that usually contains a KML file and related resources.
If the viewer is designed to be responsive, you can use it on a smartphone or tablet through a web browser.
