What is a .WLD file?
A .wld world file georeferences an image so GIS software can map it.
- Did you know
- The world file is a tiny text file holding an image’s map coordinates and scale.
- A world file holds six numbers describing an affine transformation between an image’s pixels and real-world map coordinates.
- The convention was introduced by Esri, and the file itself records no coordinate system - only scale, rotation and position.
- What Analyser reads
- Inspect geospatial and GIS files without a map: TopoJSON, OpenStreetMap XML, Esri Shapefile siblings (SHP/SHX/DBF/PRJ/CPG), world files, GML, NMEA GPS logs, IGC flight logs, MapInfo TAB/MIF, GDAL VRT, PMTiles, DTED terrain, Esri ASCII grids and SRTM .hgt - surfacing CRS/EPSG, feature/record counts, bounding boxes and elevation ranges.

- Depth of analysis
- .WLD is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .WLD file
- Drag a .WLD file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
