Convert Live GPS and Map Coordinates from WGS84 to Any CRS Powered by PROJ

From WGS84 to Thousands of Geodetic and Projected CRS

CoordFix transforms live GPS positions and map picked latitude longitude from WGS84 into thousands of EPSG systems. Use it as a precise coordinate converter and coordinate tool for field work and map visualization.

WGS84 to UTM and Popular Systems

Convert WGS84 lat long to UTM, NAD83, ETRS89 and many other geodetic and projected CRS. Handle longitude latitude conversion, grid coordinates, map projection and coordinate plotting with confidence.

Flexible Coordinate Formats

Convert in real time between Decimal Degrees DD, Degrees Decimal Minutes DMM and Degrees Minutes Seconds DMS. Choose precision, remove thousand separators for projected coordinates, or export clean values for map plotting, coordinate charts and map conversion workflows.

Built on PROJ and Trusted by Professionals

CoordFix uses the PROJ engine for accurate coordinate transformation. It is a reliable coordinate calculator for surveyors, GIS specialists and engineers.

Works Offline in the Field

After installation all transformations run locally without a data connection. Ideal for remote sites, offshore projects and low signal environments.

Export and Share Results

Save and export transformed coordinates as structured CSV. Plot coordinates on map, create a coordinate map or grid chart and share results with your team.

Input is WGS84 only. Conversion direction is from WGS84 to target CRS.
