How to Convert WGS84 to GCJ-02
WGS84 is the standard GPS coordinate system used worldwide. GCJ-02 is a regional datum required by some East Asian map providers. Convert between them when your points must align with those basemaps.
Steps
- Open the Coordinate Converter tool.
- Set the source to WGS84 and the target to GCJ-02.
- Paste your coordinates (one per line, lon,lat) or import a CSV/TXT file.
- Click convert, then copy the result or export to CSV/GeoJSON.
Tip: Tip: For about 500+ points between eligible CRS pairs, the app may use a WASM path automatically. Smaller batches use the JavaScript engine. Always verify results for surveying or legal use.
