How to Import a KML File into Google My Maps
A practical Google My Maps import workflow covering KML and KMZ preparation, layer limits, coordinate errors, styling, troubleshooting, and sharing.
To import KML into Google My Maps, create or open a map, add a layer, choose Import, and upload the KML or KMZ file. Validate the file first, keep each layer focused, and check the imported features and styles before sharing the map.
KML Validator
Check KML structure and coordinate bounds before importing the file into Google My Maps.
Prepare the KML Before Importing
Use a descriptive filename and validate the KML before opening Google My Maps. Confirm that the document contains supported Points, LineStrings, or Polygons, that coordinates use longitude-latitude order, and that the file is not unexpectedly large or dependent on unavailable NetworkLinks.
Import KML into a New Layer
Open Google My Maps, create or select a map, and add a layer. Choose Import, select the local KML or KMZ file, and wait for the features to appear. Review the layer name and feature list, then repeat the process for additional datasets when each layer has a clear purpose.
Use separate layers for boundaries, routes, points, and reference overlays so collaborators can toggle them independently.
Style and Check the Imported Features
Rename the layer, change icons or colors, and inspect the map at different zoom levels. Click several features to confirm their names and descriptions imported correctly. If a layer appears empty, zoom to its extent and check visibility before re-uploading the file.
Fix Common Import Problems
An upload error can come from malformed XML, invalid coordinates, unsupported extensions, hidden features, or a KMZ asset that is not available to the importer. Convert KMZ to KML for inspection, validate the extracted document, and preview it in a second viewer before trying again.
