Convex Hull GeoJSON Online

Wrap all GeoJSON features in the smallest enclosing convex polygon. Free browser tool, no upload required.

Drop GeoJSON file here or click to browse

Accepts: .geojson, .json

All processing happens locally in your browser. Your files never leave your device.

GeoJSON is ideal when the convex hull will feed into a web map or JavaScript pipeline — the result is a single UTF-8 file with no auxiliary files required.
