Maparz

Free GIS file converter — KML, GeoJSON, Shapefile

Visit Maparz

Maparz is a free online geospatial file converter that lets you transform vector data between ten industry-standard formats without installing any software or creating an account. You upload your file, choose an output format, and download the result — the entire conversion typically takes under five seconds regardless of file complexity. All conversions run server-side using GDAL (Geospatial Data Abstraction Library) — specifically the ogr2ogr command-line tool that powers QGIS, ArcGIS, Google Earth Engine, and PostGIS. Supported formats include Shapefile, GeoJSON, KML, KMZ, GeoPackage, GPX, DXF, GML, FlatGeobuf, and CSV. Files up to 50 MB are supported across all format pairs. Your uploaded file and the converted output are deleted from the server immediately after the download response is sent. Maparz retains no copies of your data, stores no file contents in any database, and does not use uploaded files for any purpose other than performing the requested conversion.
