Free Coordinate & GPS Tools
Convert coordinates between formats, geocode addresses, and reverse-geocode GPS points — all free, most running instantly in your browser with no sign-up.
Location Tools
Find your location, measure distances, and explore coordinates on a map — free and instant.
Your current location, GPS coordinates and address on a map — with an IP fallback if you decline access.
Open tool →Great-circle distance and bearing between two lat/long points, shown on a map.
Open tool →How far is it from your current GPS location to any city, address or coordinate?
Open tool →Find what county (or parish/borough) you're in right now using your device GPS — US Census data.
Open tool →Find what state, province or region you're in right now using your device GPS — works worldwide.
Open tool →Find the height above sea level of any lat/long (or your current location) — SRTM data, 30 m resolution.
Open tool →Initial and final bearing (azimuth) between two coordinates, with compass direction.
Open tool →Given a start, bearing and distance, calculate where you arrive — the inverse of bearing.
Open tool →Great-circle halfway point between two lat/long coordinates, with a map.
Open tool →Find the geographic centre of gravity of any number of lat/long points, plus their bounding box.
Open tool →Generate a lat/long bounding box from a center point and radius — outputs corners + GeoJSON.
Open tool →Find the point on the opposite side of the Earth — "if you dug straight down, where would you come out?"
Open tool →Find the geographic centre of any country, state, or region from its bounding box.
Open tool →Get the coordinates of any city, town or village worldwide — disambiguate with the country.
Open tool →Validate a lat/lng pair (range, precision, plausibility) and generate random valid coordinates.
Open tool →Sunrise, sunset, solar noon and twilight times for any coordinate — NOAA-accuracy, DST-aware.
Open tool →Get the IANA timezone, UTC offset, abbreviation and DST status for any lat/long.
Open tool →Coordinate Converters
Convert between coordinate formats right in your browser — no upload, no sign-up, works offline.
Convert degrees/minutes/seconds to decimal degrees and back, with the formula.
Open tool →Convert decimal degrees to DMS (degrees/minutes/seconds) and decimal minutes (DDM).
Open tool →Convert UTM zone, easting and northing to latitude/longitude (WGS84) — and back.
Open tool →Decode a Plus Code (Open Location Code) to coordinates, or encode coordinates to one.
Open tool →Decode a geohash to coordinates or encode lat/long to a geohash, shown on a map.
Open tool →Convert Military Grid Reference System coordinates to latitude/longitude and back.
Open tool →Convert EPSG:3857 X/Y metres to lat/long (EPSG:4326) — the projection every web map uses.
Open tool →Convert Earth-Centered Earth-Fixed Cartesian coordinates to lat/lng/height (WGS84, Bowring).
Open tool →Convert decimal degrees to degrees decimal minutes — the marine and aviation GPS format.
Open tool →Geocode any street address or place name to a Google Plus Code. Powered by our free geocoder.
Open tool →Convert lat/long to a Maidenhead (QTH) grid square for ham radio, and back.
Open tool →Reproject coordinates between WGS84, Web Mercator, all UTM zones, and national grids (proj4).
Open tool →Paste any coordinate — decimal, DMS, UTM, MGRS, Plus Code or geohash — auto-detect and convert to lat/long.
Open tool →Paste a whole list of coordinates (any format, mixed) and get a clean CSV of decimal lat/long.
Open tool →Convert Well-Known-Text geometry to GeoJSON and back — Point, Line, Polygon, Multi and Collections.
Open tool →Convert GPS track files between GPX, KML and GeoJSON — waypoints, tracks, routes and polygons.
Open tool →Paste a CSV of lat/long points and plot them on a map — auto-detect columns, colour by any field.
Open tool →Unit Converters
Quick conversions between the units used in mapping, surveying, and navigation.
Metres, kilometres, miles, feet, yards, inches, and nautical miles — live as you type.
Open tool →Hectares, acres, km², m², ft², mi², sections — live conversions.
Open tool →Convert degrees, radians and gradians, with the exact formula and a fraction-of-π view.
Open tool →Geocoding Tools
Turn addresses into coordinates and coordinates into addresses, powered by the free LatLng API.
Developer APIs
Free-tier REST APIs behind the tools above — 3,000 requests/day, no credit card.
Forward geocoding: addresses and place names to coordinates.
Open tool →Coordinates to addresses, at scale.
Open tool →Geocode whole lists of addresses in one job.
Open tool →Search-as-you-type address and place suggestions.
Open tool →OpenStreetMap vector tiles for MapLibre GL JS.
Open tool →Map images (PNG/JPEG) from a single URL.
Open tool →All the coordinate tools you need, in one place
Working with locations means constantly switching between formats. Paper maps and GPS units use degrees, minutes, seconds; surveyors and GIS use UTM; Google Maps shows Plus Codes; and every API and database wants plain decimal degrees. These free tools convert between all of them — and turn addresses into coordinates and back.
- No sign-up, no cost. The converters run entirely in your browser; the geocoders use the free LatLng API tier.
- Accurate. Conversions use standard WGS84 formulas and the official Open Location Code algorithm.
- Private. Coordinate conversions never leave your device.
