About Maparz

Our mission

Geospatial data format conversion should be free, instant, and accessible to everyone — whether you are a seasoned GIS analyst or someone who just received a Shapefile and needs to view it on Google Earth. Maparz removes the barriers: no account, no waiting, no credit card. Just upload and convert.

Technology

Maparz is powered by GDAL (Geospatial Data Abstraction Library), the industry-standard open-source toolkit used by QGIS, ArcGIS, Google Earth Engine, PostGIS, and thousands of other GIS applications worldwide. Specifically, we use ogr2ogr, GDAL's powerful command-line vector conversion tool, to perform all format conversions server-side.

The backend is built on FastAPI (Python) and the frontend is a static Next.js application. Map previews are rendered using Leaflet.js with CartoDB's dark tile layer.

Privacy & data handling

Your files are processed on our server and deleted immediately after the conversion is complete. We do not store, log, index, or share your uploaded data with any third party. No account is required, and we collect no personally identifiable information beyond standard web server logs (IP address, user agent) which are retained for up to 7 days for security and abuse prevention.
