Dissolve Shapefile Online
Merge polygon features into a single geometry, or dissolve by a shared attribute value.
Powered by GDAL WebAssembly and Turf.js for accurate geometry dissolve.
Shapefile is the right choice when the dissolved output needs to open in older versions of ArcGIS, MapInfo, or other legacy desktop GIS software. Upload as a ZIP containing .shp, .dbf, and .prj.
