## 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.

## Inputs

- **KML Input** (textarea): Enter KML data...
- **Pretty Print Output** (checkbox)

## 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

- Web developers building interactive maps using Leaflet or Mapbox.
- Data analysts preparing spatial datasets for visualization in browser-based dashboards.
- GIS professionals standardizing legacy KML files for modern cloud-based mapping infrastructure.

## Frequently asked questions

### 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.
