Edit Metadata
Change document and track names, descriptions, and timestamps. Fix incorrectly labeled routes before sharing or importing into other applications.
Trim Routes
Remove unwanted portions from the start or end of your track. Great for cutting out sections you don't want to include when sharing your route.
Adjust GPS
Apply GPS coordinate offsets to fix shifted tracks. Useful when routes look displaced due to device or map projection issues.
What is a KML File Editor?
A KML file editor allows you to modify the data stored in .kml files, which are commonly used with Google Earth and other mapping applications. You can update document names, trim routes, adjust GPS coordinates, and edit placemark information before exporting the edited KML for use elsewhere.
What is KML?
KML (Keyhole Markup Language) is an XML-based format for representing geographic data. It was originally developed for Google Earth and is now an international standard (OGC KML). KML files can contain points, lines (tracks/routes), polygons, and rich styling information for visualization in mapping applications.
Is my data safe?
Yes. Everything runs locally in your browser. Your KML file is never uploaded to any server. Your original file remains unchanged until you download the edited version.
What can I edit?
You can change document and track names, trim routes, adjust GPS coordinates, and modify timestamps (for gx:Track data). The editor supports both gx:Track (activity data with timestamps) and LineString (static routes) elements.
Works with Google Earth
KML files edited with this tool are fully compatible with Google Earth, Google Maps, and any other application that supports the KML format. Your edited tracks will display correctly with all metadata preserved.
Your Privacy is Protected
Your KML files are processed entirely in your browser. No data is ever uploaded to our servers. Your GPS tracks and locations stay on your device.
