Geocoding Tool
Convert between addresses and coordinates using OpenStreetMap data. Search for a place to get its coordinates, or click the map to find the address. All queries use the free Nominatim API — no API key required.
Forward & Reverse Geocoding in Your Browser
Convert addresses to coordinates and coordinates to addresses using OpenStreetMap's global dataset — results appear instantly on the map.
Forward Geocoding
Type an address, place name, or landmark and get precise coordinates. Results are ranked by relevance and shown as numbered markers on the map with detailed address breakdowns.
Reverse Geocoding
Click anywhere on the map to discover the address at that location. Get the full address, structured components (road, city, state, country), and exact coordinates.
Shareable Links
Your search query, mode, coordinates, and selected result are encoded in the URL. Share the link with colleagues to reproduce the exact geocoding state.
