FAQ
Do I need to upload my Shapefile?
No. Everything runs locally in your browser for privacy and speed.
What should be inside the .zip?
At minimum .shp and .dbf. Including .prj helps detect CRS (WGS84 vs Web Mercator).
WKB vs EWKB — what’s the difference?
EWKB can embed SRID. Enable “Include SRID” to export EWKB (useful for PostGIS).
Do you support polygons only?
The tool can read all geometry types. You can optionally filter to Polygon/MultiPolygon before export.
