About

This tool merges KML files into a single layer. The files are not uploaded, but are processed within the browser. Currently, KMZ files are not supported but you can unzip them yourself. Any unknown file types or malformed files are skipped. Large files are likely to be problematic. Tested using Chrome. Feel free to view the source and make your own modifications. Email us if you run into issues or have a feature request: brassmonkery @ gmail.com.

Instructions

Select 2 or more KML files to merge into a single layer.

Optional - Merge Method

This method uses's Mapbox's toGeoJson library to convert the kml file to geojson and then converts it back to KML using their toKml library. This removes styles, but results in a 'cleaner' output file. If you've used the site in the past, this is what was being used.

Now available on the Windows Store!

Tired of this website? You can now use the "XML" Merge Method offline by purchasing KmlMerger for Windows and help support me.
