How do I convert WGS84 coordinates online?

Open the coordinate converter, set source to WGS84 (or EPSG:4326), choose a target such as EPSG:3857 or UTM, paste lon,lat lines or import CSV, then convert and export.

Can I convert EPSG:4326 to EPSG:3857?

Yes. Set source to EPSG:4326 (WGS84) and target to EPSG:3857 (Web Mercator). The tool converts batches in your browser.

Does the converter support UTM?

Yes. Pick a UTM EPSG zone as the target (for example EPSG:32633 for UTM zone 33N) or search the EPSG catalog for your zone.

Are my coordinates uploaded to a server?

No. Conversion runs entirely in your browser with JavaScript and WebAssembly. Files never leave your device.
