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.
Coordinate Converters
Convert between coordinate formats right in your browser — no upload, no sign-up, works offline.
DMS ↔ Decimal Degrees
InstantConvert degrees/minutes/seconds to decimal degrees and back, with the formula and worked examples.
Open tool →UTM ↔ Lat/Long

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.
