Simplify GeoPackage Online

Reduce GeoPackage file complexity and size using the Douglas-Peucker simplification algorithm

Powered by GDAL WebAssembly for accurate geometry simplification.

Simplifying a GeoPackage in the browser is a quick way to create a display-optimised version of a detailed analysis layer before publishing it as a web map or sharing it with stakeholders who do not need full resolution.
