Convert between latitude/longitude and Google's Plus Codes (Open Location Codes). All calculations run locally — no API calls.
The Open Location Code is an open-source encoding of any place on Earth into a short alphanumeric code with a + separator. Codes use a 20-character base ("23456789CFGHJMPQRVWX") chosen to avoid ambiguous characters and accidental words. The longer the code, the smaller the area it represents. This tool implements the full encoding and decoding algorithm — no network calls, no external libraries.
