🧭 GeoJSON to WKT Converter
Paste a GeoJSON geometry (or Feature) and get OGC WKT like POLYGON ((…)), ready for PostGIS or a spatial query, converted locally.
GeoJSON geometry → OGC WKT
How the geojson to wkt converter works
The tool parses your GeoJSON and serialises the geometry as OGC Well-Known Text, the format spatial databases and SQL functions (PostGIS ST_GeomFromText, spatial indexes, many GIS tools) expect. It accepts a bare geometry, a Feature (it uses the Feature's geometry), or a FeatureCollection (emitted as a GEOMETRYCOLLECTION), and it preserves X Y (longitude latitude) order and polygon holes. Point, LineString, Polygon and their Multi* variants are all supported.
This is the inverse of the WKT-to-GeoJSON tool and is handy when you have GeoJSON from a web map but need to insert it into a spatial database or pass it to a WKT-based function. Note that WKT represents geometry only, so any Feature properties are dropped in the conversion, the geometry is what carries over. It runs entirely in your browser, keeping location data on your device.
Frequently asked questions
How do I convert GeoJSON to WKT?
Paste a GeoJSON geometry, Feature or FeatureCollection (or load a .geojson file) and the tool outputs the equivalent WKT you can copy or download, for example a Polygon becomes POLYGON ((…)).
Can I paste a Feature or FeatureCollection?
Yes, a Feature is converted using its geometry, and a FeatureCollection becomes a GEOMETRYCOLLECTION of the features' geometries. A bare geometry object works too.
Is this the format PostGIS uses?
Yes, WKT is what functions like ST_GeomFromText('POINT(30 10)') expect, so this output drops straight into PostGIS and other spatial-SQL databases. Add the SRID separately if your column requires one.
What happens to my Feature's properties?
They're dropped, because WKT encodes geometry only. There's nowhere to put attributes. Keep the properties separately (e.g. in the database row) alongside the WKT geometry.
Is my GeoJSON uploaded?
No, the conversion runs locally in your browser and nothing is transmitted.
