Terms of Use

Last updated: 2 May 2026.

Service

EPSG Transform is provided free of charge for the public to use. By using this site you agree to use it lawfully and not to attempt to disrupt or abuse the service.

No warranty

Coordinate transformations are provided “as is” with no warranty of fitness for any particular purpose. While we use the official EPSG Geodetic Parameter Dataset and the well-tested PROJ / proj4js implementation, results from this site MUST NOT be used as the sole basis for decisions where coordinate accuracy is legally, commercially or safety-critical (cadastre, surveying, navigation, engineering compliance). For such use cases, employ a desktop GIS or official conversion service that applies the appropriate grid-shift transformations.
