Convert any GIS file in your browser. Nothing is uploaded.

What GISConverters does

GISConverters converts vector, CAD, GPS and tabular geodata between the formats mapping people actually swap files in: KML and KMZ from Google Earth, Esri Shapefiles, GeoJSON for web maps, GeoPackage, GPX tracks, DXF drawings, and CSV or Excel tables that carry latitude and longitude columns. It reprojects coordinates between systems too, so data written in WGS84 (EPSG:4326), Web Mercator (EPSG:3857) or a UTM zone lands where it should. It does not touch imagery or raster grids; this is a features-and-attributes tool, not a picture converter.

How it works

Under the hood is GDAL/OGR, the same open-source engine that powers QGIS and most professional GIS software, compiled to WebAssembly so it runs as code inside your browser tab. There is no server in the loop. When you drop a file, it is read from your own machine's memory, converted locally, and handed straight back to you as a download. Because nothing is uploaded, GISConverters is safe for sensitive data you cannot send to a third-party server, such as client parcels, survey points or unpublished site boundaries.

Three steps

1. Drop your file. Drag any supported file onto the box, or click to browse. The format is detected in the browser and the possible outputs appear.

2. Pick the output and, if needed, a coordinate system. Choose the target format; optionally set an EPSG code to reproject. A map preview confirms the data is where you expect before you commit.

3. Convert and download. The conversion runs on your device in seconds and the result downloads directly. Shapefiles arrive zipped, so their .shp, .shx, .dbf and .prj parts stay together.

Which format do you need?

• You need to open the data in Google Earth or share a lightweight map by email → KML or KMZ. Both are Google Earth's native format and keep colors, icons and description balloons; KMZ is just a zipped KML that is smaller to send.
• You need an editable layer for QGIS, ArcGIS or another desktop GIS → Shapefile or GeoPackage. Shapefile is the desktop lingua franca (delivered zipped), while GeoPackage packs many layers and long field names into a single .gpkg with no shapefile limits.
• You need to drop the data into a web map like Leaflet or Mapbox → GeoJSON. It is RFC 7946, always WGS84, human-readable text that web mapping libraries read directly with no conversion step.
• You need to load points, routes or tracks onto a GPS unit or fitness app → GPX. GPX is the interchange format handheld GPS devices and apps expect, with waypoints, routes and tracks in WGS84.
• You need to hand geometry to AutoCAD or an engineering CAD tool → DXF. DXF organizes geometry by drawing layers for CAD, though note it carries no attribute table and usually no coordinate system.

Popular conversions

Most visitors arrive for one of a handful of jobs. To move Google Earth work into desktop GIS, convert KML to a shapefile; to go the other way and view a GIS layer in Google Earth, turn a shapefile into KML. To map a spreadsheet of coordinates, convert CSV to KML. For web mapping, convert KML to GeoJSON, and to unpack a zipped Google Earth file, extract KMZ to KML.

Supported formats

GISConverters handles vector, CAD, GPS and spreadsheet formats. It does not convert raster imagery such as GeoTIFF, which needs different handling, and AutoCAD's binary DWG must be exported to DXF before it can be read here.
