GeoJSON and WKT Conversion
Convert bidirectionally between GeoJSON geometry and WKT. Input is parsed in the browser, and the converted geometry is shown on the map.
Use a dedicated page below to open a specific direction immediately. This changes the format only; it does not reproject the coordinate system.
How to use it
- Pick the conversion direction (GeoJSON→WKT or WKT→GeoJSON).
- Paste or type the geometry.
- Review the converted result and the map preview.
Frequently asked questions
Does it handle Multi* geometries?
Yes — MultiPoint, MultiLineString, MultiPolygon, and GeometryCollection all convert in both directions.
Why does invalid WKT throw an error instead of just converting?
Silently guessing at a structurally invalid input, like an unclosed ring, risks producing a plausible-looking but wrong shape, so structural validation runs before conversion.
