Everything you need to work with geospatial data
Built for GIS professionals, developers, and anyone who works with geographic data.
GDAL-Powered Conversions
Conversions use ogr2ogr, the same engine behind QGIS, ArcGIS, and Google Earth Engine.

Geospatial conversion should be free and accessible to everyone
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 GIS applications worldwide. Specifically, we use ogr2ogr, GDAL's vector conversion tool, to perform all format conversions server-side.
GDAL handles the full complexity of geospatial conversion: reading and writing binary format headers, reprojecting coordinate reference systems using the PROJ library, mapping attribute field types between formats, and managing geometry encoding differences between vector specifications. Using GDAL means that Maparz conversions are format-compliant by specification, not by approximation — the same engine that government agencies and enterprise GIS teams rely on in production is the one running every conversion on this site.
Our approach to geospatial conversion
Geospatial file conversion sounds simple, but it hides a surprising number of edge cases. A Shapefile's .dbf attribute table truncates field names to ten characters — so converting a dataset that has longer field names requires careful handling to avoid silent data loss. GeoJSON per RFC 7946 must always be in WGS 84, which means reprojecting the source CRS automatically rather than passing through projected coordinates that violate the standard. KMZ is a ZIP-compressed KML archive, which means GDAL must unpack it before reading — a step that fails silently in many naive converters.
Maparz handles these cases correctly because it delegates them entirely to GDAL rather than implementing its own format parsing. Every conversion pair on this site has been tested with real-world files to verify that the output is valid, opens in the target application, and preserves all attribute data that the destination format can carry. Where a format imposes hard limits — such as the Shapefile field name length cap — the documentation on each converter page explains what to expect.
Privacy is built into the architecture, not bolted on. Files are processed in ephemeral temporary directories and deleted immediately after the download response is sent — not when a session expires or a cron job runs, but at the moment the conversion completes. There is no persistent storage of uploaded geospatial data, no logging of file contents, and no third-party cloud storage involved in the conversion pipeline.
