Example

Input:  POINT (28.9784 41.0082)  [EPSG:4326]
Output: POINT (3220985.2 5049499.6)  [EPSG:3857]

How to Use the WKT Projection Converter

Paste your WKT geometry string into the input field.
Select the source EPSG code (the CRS of your input geometry).
Select the target EPSG code (the CRS you want to convert to).
Click Convert to get the reprojected WKT geometry string.
Copy or export the result for use in your GIS application.

WKT Projection Converter – Frequently Asked Questions

How is this different from the Coordinate Converter?

The WKT Projection Converter reprojects entire WKT geometry strings — including complex polygons with hundreds of vertices — while the Coordinate Converter converts individual coordinate pairs.

What WKT geometry types can be reprojected?

All OGC WKT types: POINT, LINESTRING, POLYGON, MULTIPOINT, MULTILINESTRING, MULTIPOLYGON and GEOMETRYCOLLECTION.

Can I reproject from EPSG:4326 to a UTM zone?

Yes — enter the UTM zone EPSG code (e.g. 32633 for UTM Zone 33N) as the target CRS. The tool supports all registered UTM zones.

Is there a limit on geometry complexity?

No server-side limit. Conversion happens in the browser using proj4js and handles geometries of any size and complexity.

Does it support EWKT with SRID prefix?

The tool accepts WKT geometry strings. If you have EWKT, strip the SRID prefix before pasting or use the source EPSG selector to specify the input CRS.
