WKT ↔ GeoJSON Converter
Convert between WKT and GeoJSON formats instantly.
Online WKT GeoJSON Converter
Rodosto WKT Converter is a free online tool that lets you instantly perform bidirectional conversion between Well-Known Text (WKT) and GeoJSON formats. Paste your geometry data, convert, and preview it on the map right away.
Supported Geometry Types
- Point: Single point coordinates
- LineString: Line and route data
- Polygon: Area and boundary data
- MultiPoint, MultiLineString, MultiPolygon: Multi-part geometries
- GeometryCollection: Mixed geometry collections
How to Use
Paste your WKT text in the top box and click "WKT → GeoJSON". Or paste your GeoJSON data in the bottom box and click "GeoJSON → WKT". The converted data is automatically displayed on the map.
Secure & Client-Side
Just like our GeoJSON Formatter and Coordinate Converter, this tool processes your data entirely in your browser. No data is ever sent to a server.
Frequently Asked Questions
What is WKT and where is it used?
WKT (Well-Known Text) is an OGC standard for representing geometric shapes as text strings. It is supported by PostGIS, Oracle Spatial, QGIS, ArcGIS, and most GIS software. Example: POINT(28.9784 41.0082) or POLYGON((...))
Why convert WKT to GeoJSON?
GeoJSON is more widely used in web mapping applications (Leaflet, Mapbox, Google Maps API). If you retrieve geometries from a spatial database as WKT, you need to convert them to GeoJSON to display them in a web map.
Which geometry types are supported?
POINT, LINESTRING, POLYGON, MULTIPOINT, MULTILINESTRING, MULTIPOLYGON, and GEOMETRYCOLLECTION are all supported. Both WKT→GeoJSON and GeoJSON→WKT conversions are bidirectional.
