GIS File Converter

Convert between KML, KMZ, Shapefile, GeoJSON, GPX and CSV. Drop a file, pick what you want out of it, and download the result. Everything runs in your browser, so your data never leaves your computer and there is no limit on file size.

Your file is converted inside this tab and never uploaded. No size limit, no sign-up.

Why it runs in your browser

Nothing is uploaded

Files are read and converted inside your browser tab. No server ever sees them, which matters when the data is under a confidentiality clause.

No size limit, no sign-up

There is no upload, so there is nothing to meter. Convert a 500 MB shapefile as easily as a 5 KB one, as often as you like.

Instant, and works offline

No queue and no round trip. Load this page once, disconnect from the internet, and it still converts.

Common conversions

Each of these has its own page explaining exactly what survives the conversion and what does not.

Convert KML to ShapefileGoogle Earth KML to a zipped shapefile set, with the attribute table intact Convert Shapefile to KMLShapefile to Google Earth KML, reprojected to WGS 84 automatically Convert KML to KMZPack a KML into a KMZ with nothing changed, at a fraction of the size Convert KMZ to ShapefileGoogle Earth KMZ straight to a zipped shapefile, without unpacking it first Convert KMZ to KMLExtract the KML from a KMZ archive, byte for byte Convert KML to GeoJSONKML to GeoJSON with full-length property names and styling preserved

Formats it handles

KML.kml · Keyhole Markup Language

The XML format Google Earth uses. One readable text file that holds points, lines and polygons together with their names, descriptions and colours.

KMZ.kmz · Zipped Keyhole Markup Language

A KML file and its images, icons and overlays packed into a single zip with a .kmz extension. Smaller to send, and the one file carries everything it needs to draw.

Shapefile.shp · Esri Shapefile

The format every GIS reads. Not one file but a set: .shp for geometry, .dbf for the attribute table, .shx for the index and .prj for the coordinate system, which travel together in a zip.

GeoJSON.geojson · GeoJSON

The web's geospatial format: plain JSON that every mapping library, API and modern GIS reads directly. Always in WGS 84 longitude/latitude.

GPX.gpx · GPS Exchange Format

What handheld GPS units and fitness apps export: waypoints, routes and tracks, with elevation and timestamps.

CSV.csv · Comma-Separated Values

A spreadsheet table with a latitude and a longitude column. Only holds points unless the geometry is written out as WKT text.

AutoCAD DWG, Esri File Geodatabase and MapInfo TAB are not here. Those are closed binary formats that cannot be read in a browser without a server doing the work, and we would rather leave them out than upload your files to provide them.
