Free Online GIS File Converter
MapfileConverter is a free, browser-based tool for converting geographic and spatial data files. Whether you need to convert GeoJSON to Shapefile, transform KML files from Google Earth into GeoJSON, or convert GPX tracks into other mapping formats, our converter handles it all instantly in your browser.
Unlike other online converters, MapfileConverter processes your files entirely on your device using client-side JavaScript. Your geographic data is never uploaded to a server, making it the most privacy-friendly GIS conversion tool available. This is especially important for professionals working with sensitive location data, property boundaries, infrastructure mapping, or other confidential geospatial information.
Our converter supports all major GIS and mapping formats including GeoJSON, Shapefile (SHP), KML/KMZ (Google Earth), GPX (GPS Exchange), DXF (AutoCAD), and OSM (OpenStreetMap). Simply upload your file, select the target format, and download the converted result in seconds.
Supported Map File Formats
GeoJSON
The standard format for web mapping. Lightweight, human-readable, and supported by all modern mapping libraries like Leaflet and Mapbox.
Shapefile (SHP)
The industry-standard GIS format by Esri. Widely used in professional GIS software including ArcGIS, QGIS, and MapInfo for spatial analysis.
KML / KMZ
Google Earth's native format. Perfect for visualising geographic data with styling, 3D views, and annotations in Google Earth Pro and Maps.
GPX
GPS Exchange Format for tracks, routes, and waypoints. Used by fitness apps, outdoor navigation devices, and GPS tracking software.
DXF
AutoCAD Drawing Exchange Format. Bridges the gap between CAD engineering drawings and GIS mapping data for construction and surveying.
OSM
OpenStreetMap data format. Convert community-contributed map data into standard GIS formats for analysis and visualisation.

Frequently Asked Questions
Is MapfileConverter really free?
Yes, MapfileConverter is completely free to use. There are no limits on the number of conversions, no hidden fees, and no registration required. Simply upload your file and convert instantly.
How does client-side processing work?
Unlike most online converters, MapfileConverter runs entirely in your web browser using JavaScript. When you upload a file, it is read and processed locally on your computer. The file is never sent to any server, making it the most secure option for converting sensitive geographic data.
What map file formats are supported?
We support GeoJSON, Shapefile (SHP/ZIP), KML, KMZ, GPX, DXF, OSM, TopoJSON, GML, WKT, GeoPackage, and CSV. You can convert between any supported pair of formats.
Can I convert Google Earth KML files?
Yes, MapfileConverter fully supports KML and KMZ files from Google Earth. You can convert them to GeoJSON, Shapefile, GPX, or DXF. We also support converting other formats into KML for use in Google Earth.
What is the maximum file size?
Since processing happens in your browser, the maximum depends on your device's memory. Files up to 50 MB convert quickly. Files between 50-200 MB may take longer. We recommend splitting very large files before converting.
Do I need to install any software?
No. MapfileConverter works directly in any modern web browser, including Chrome, Firefox, Safari, and Edge. There is nothing to install or configure.
