SHP to GeoJSON Converter - Shapefile to GeoJSON Online

What is SHP to GeoJSON Conversion?

SHP to GeoJSON converter transforms Esri Shapefile data into GeoJSON format for modern web mapping. A Shapefile is not a single file but a set of files — .shp for geometry, .shx for index, .dbf for attributes, and .prj for projection. GeoJSON, on the other hand, is a single JSON-based standard (RFC 7946) natively supported by Leaflet, Mapbox GL, OpenLayers, and most GIS APIs. Converting shapefile to GeoJSON makes legacy GIS data instantly usable on the web without desktop software.

Why convert shapefile to GeoJSON? Shapefiles are binary and cumbersome for the web; GeoJSON is text, human-readable, and directly renderable in JavaScript. If you search for shp converter to geojson or shp file conversion, you typically need to publish parcel boundaries, points of interest, or administrative polygons online. Our tool performs convert shapefile to geojson entirely client-side, preserving all attribute fields from DBF as properties and automatically handling projection if a PRJ is present.

How to Convert Shapefile ZIP to GeoJSON Online

Using this tool: prepare a ZIP where all components share the same basename, e.g., roads.shp, roads.shx, roads.dbf, roads.prj. Drop it into the converter, set coordinate precision to reduce file size (6 decimals ~ 10cm accuracy is default for web maps), toggle Reproject to WGS84 to ensure output is EPSG:4326, and optionally include bbox for quick extent checks. Click Convert — the button disables, shows a spinner, and smoothly scrolls to the result area. You get feature count, geometry types (Point, LineString, Polygon, etc.), output size, a Leaflet preview, and formatted output with Copy, Download, Clear, and Fullscreen actions.

Example: A municipal parcels ZIP with 1,240 polygons and 8 attribute fields converts to a ~2.3 MB GeoJSON. With precision 5 and minify off, it becomes ~1.8 MB, loads instantly in Leaflet via L.geoJSON(data).addTo(map). Usage includes choropleth maps, spatial analysis in Turf.js, or import into QGIS and Mapshaper. Because conversion is local, even confidential infrastructure shapefiles stay private.

For best SEO and interoperability, keep property names ASCII, avoid field names longer than 10 characters (DBF limit), and ensure your PRJ is valid WKT. If reprojection is enabled, our converter uses the PRJ metadata via shpjs to output WGS84, which is required by most web maps. Need more?
