Overview
The KML to GeoJSON Converter is a streamlined utility designed to transform geographic data from Keyhole Markup Language (KML) into the widely supported GeoJSON format, ensuring seamless compatibility with modern web mapping libraries and GIS applications.
When to Use
- •When you need to integrate KML map data into web applications that require GeoJSON input.
- •When migrating geographic features from Google Earth or legacy mapping tools to modern GIS platforms.
- •When you need to standardize spatial data formats for better interoperability across different mapping software.
How It Works
- •Paste your KML source code directly into the input field.
- •Toggle the 'Pretty Print' option if you require human-readable, indented JSON output.
- •Click the convert button to instantly generate your GeoJSON data.
- •Copy or download the resulting GeoJSON code for use in your project.
Use Cases
Examples
1. Migrating Map Markers for Web Display
Frontend Developer- Background
- The team has a set of store locations saved as a KML file from an older internal tool.
- Problem
- The new web map component only accepts GeoJSON, making the existing KML file incompatible.
- How to Use
- Paste the KML content into the input area, ensure 'Pretty Print' is checked, and convert.
- Outcome
- A clean, valid GeoJSON file ready to be imported into the web map application.
2. Standardizing Spatial Data for GIS
GIS Analyst- Background
- A project requires merging multiple geographic layers from different sources into a single repository.
- Problem
- The source files are in KML, but the central database requires GeoJSON for consistent API handling.
- How to Use
- Input the KML data and convert to generate the standardized GeoJSON structure.
- Outcome
- The data is successfully converted, allowing for seamless integration into the central GIS database.

FAQ
What is the difference between KML and GeoJSON?
KML is an XML-based format primarily used by Google Earth, while GeoJSON is a lightweight, JSON-based format optimized for web-based mapping and JavaScript applications.
Does this tool support large KML files?
Yes, the tool is designed to handle standard KML files efficiently, though extremely large datasets may require a stable internet connection for processing.
What is the 'Pretty Print' option?
Enabling 'Pretty Print' formats the output with indentation and line breaks, making the resulting GeoJSON file much easier to read and debug.
Is my data stored on your servers?
No, this tool processes your data locally or in-memory, and we do not store or retain your geographic information after the conversion is complete.
Can I convert GeoJSON back to KML?
This specific utility is designed for KML to GeoJSON conversion only; please check our other tools for reverse format support.
