Online GIS Converter

Convert KML to GeoJSON.

Convert KML to GeoJSON for cleaner web mapping, analysis, and data exchange. The app inspects your KML first, then converts placemarks and geometries through GDAL.

Inspect before you spend: review your file metadata first, then convert it with a GDAL-powered workflow. Failed conversions do not cost tokens.

What happens when you convert KML to GeoJSON?

KML to GeoJSON, explained

KML to GeoJSON conversion turns Google Earth-style KML placemarks into GeoJSON features. Geometry and attributes are preserved where possible, while KML-specific display concepts such as folders and styles may not map directly into GeoJSON.

Check these details first.

  • Upload a .kml file that GDAL can read.
  • Use KML files with standard placemarks, lines, and polygons for best results.
  • Inspect the detected geometry and feature count before converting.
  • If you have a KMZ archive, use a KMZ-capable conversion workflow when available.

What may not carry over perfectly.

  • KML styling, icons, folders, and display metadata may not carry over as GeoJSON styling.
  • Nested KML structures can flatten into simpler feature properties.
  • Network links and dynamic KML references may not behave like embedded features.
  • Very large KML files may produce large GeoJSON outputs.
01

Inspect

Upload the source file and review detected metadata before tokens are used.

02

Choose Output

Keep GeoJSON selected or adjust conversion settings if needed.

03

Convert

Run the GDAL-powered conversion on the server.

04

Validate & Download

Completed outputs are inspected again and stored temporarily for download.

01 What happens to KML styles when converting to GeoJSON?
GeoJSON stores geometry and properties, not full KML styling. Some style-related fields may become properties, but map appearance usually needs to be recreated in your target tool.
02 Can I convert Google Earth KML files to GeoJSON?
Yes, standard KML placemarks from Google Earth-style workflows are a common use case.
03 Is KML to GeoJSON good for web maps?
Yes. GeoJSON is usually easier to use in web mapping libraries and APIs than KML.
04 Does the app inspect KML before conversion?
Yes. It checks whether the file is readable and shows detected metadata before tokens are spent.

Temporary files, clear retention, no surprise token spend.

Uploads and outputs are temporary and currently designed around 7-day retention. Files are used for inspection and conversion, not public sharing. You can review conversion history after signing in.
