Free Online Map Tools & Geographic Calculators

496 browser-based geographic tools, grouped into 14 task hubs so you can tell which page is the authority for a question. Every tool is free, works worldwide unless it is marked as US-focused, and needs no account.

Start with a hub if you know the job — distance calculators, radius and service area maps, coordinate converters or KML, GPX and GeoJSON tools — or use the search box below to filter the full directory by keyword.
