Convex Hull GeoJSON Online

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

Powered by GDAL WebAssembly and Turf.js for accurate convex hull calculation.

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.
