Shapefile Validator — free & private
Upload a zipped Shapefile (.zip). Validate Polygon/MultiPolygon rings, holes, duplicates, self-intersections — and optionally export a fixed Shapefile ZIP.
FAQ
Does this upload my Shapefile?
No. Parsing, validation, and exports run entirely in your browser.
What input do you accept?
A zipped Shapefile (.zip) containing at least .shp and .dbf (and optionally .prj).
Do you validate all geometry types?
This validator focuses on Polygon/MultiPolygon. Non-polygon features are skipped (count shown).
What coordinate system is assumed?
Validation warnings assume WGS84 lon/lat. If your shapefile is projected (UTM/meters), you’ll see out-of-range warnings and the map preview won’t make sense until reprojected.
