KML Viewer
Online KML viewer — drop a .kml or .kmz file to view it on an interactive map without Google Earth

What is a KML file?
KML (Keyhole Markup Language) is an XML-based format originally developed by Keyhole and adopted by Google for representing geographic features in Google Earth and Google Maps. It is now an OGC standard and one of the most widely shared map data formats — surveyors, drone pilots, conservation groups, and government agencies all exchange data in KML.
KMZ is the same data, but compressed into a single .kmz archive that can also bundle icons, overlays, or imagery. Both KML and KMZ work in this viewer — drop either one in.
When you would use an online KML viewer
Quick preview without Google Earth
You received a KML from a client or colleague and just want to see it on a map. Skip the Google Earth install and view it in your browser.
Checking drone or survey output
Drone software, GPS units, and survey tools commonly export to KML. Confirm the boundaries or flight paths captured what you expected before uploading to a CAD or GIS pipeline.
Opening Google My Maps exports
When you export a Google My Maps layer you get a KMZ. View it here without needing a Google account or the My Maps interface.
Auditing real-estate or property boundaries
Many parcel-mapping tools deliver KML. Open it here to verify coordinates before printing to PDF or converting to Shapefile for CAD work.
How to view a KML or KMZ file online
- Drag your
.kmlor.kmzfile onto the viewer above (or click to browse). - The placemarks, paths, and polygons render on an interactive map.
- Pan, zoom, and click any feature to read its name, description, and attributes.
- No Google Earth or signup is needed — the file is parsed in your browser.
KML features supported by this viewer
- • Point placemarks (with name and description popups)
- • LineString paths (tracks, routes, trails)
- • Polygons (parcels, regions, footprints)
- • MultiGeometry features
- • Folders and document nesting
- • Embedded styling (colours and basic icons)
- • Compressed KMZ archives
- • KML exports from Google My Maps and Google Earth
Frequently Asked Questions
How do I view a KML file online without Google Earth?
Drop your .kml or .kmz file onto the viewer above. The placemarks, paths, and polygons render on an interactive map immediately — no Google Earth, no Google account, and no software install.
Can I view KMZ files as well as KML?
Yes. KMZ is simply a zipped KML file (often with embedded icons or imagery). This viewer unzips KMZ in your browser and renders the contents the same way as plain KML.
What can a KML file contain?
KML supports placemarks (point features), paths (LineStrings), polygons, multi-geometry features, ground overlays, screen overlays, and styling rules. This viewer renders all standard vector geometry types from the KML 2.2 spec.
Is my KML data uploaded to a server?
No. The KML viewer parses your file entirely in your browser using client-side JavaScript. Nothing is uploaded — your data stays on your device, which is essential for confidential or proprietary KMLs.
Why does my KML look different from Google Earth?
KML allows extensive styling — colours, icons, label visibility. This viewer renders standard placemark, line, and polygon geometry with sensible defaults. Custom icons or 3D extrusions from Google Earth may not be reproduced exactly, but all geographic features will be in the correct location.
Can I open a Google My Maps export here?
Yes. When you export a layer from Google My Maps you receive a KML or KMZ file — drop it into this viewer and it will display every layer just like in My Maps, without needing to log in to Google.
What if I need to convert my KML to another format?
Once you have confirmed the data is what you expect, use our converters — KML to GeoJSON, KML to Shapefile, KML to PDF, KML to Excel — all run in your browser the same way as this viewer.
KML files from Google Earth or Google My Maps often contain placemarks, paths, and polygons with embedded style data — viewing the file here gives you a map preview and attribute inspection without launching Google Earth.
