About This Tool

Purpose built to enable browser-based shapefile editing for non-desktop GIS workflows. It accepts shapefile sets, preserves geometry validity, and supports attribute modifications, reprojection, and export. The tool uses standard vector operations to adjust points, lines, and polygons and performs lightweight topology checks to prevent obvious errors.
Users upload .shp/.shx/.dbf and an optional .prj or a ZIP archive. After editing, the tool can reproject to a selected CRS, then export a ZIP shapefile or GeoJSON for downstream GIS tasks. It targets GIS analysts, urban planners, researchers, and data engineers who need rapid in-browser edits without installing software.
Unique value comes from in-browser processing, immediate feedback on geometry validity, and a streamlined export path that preserves schema and allows batch attribute edits when needed.

Frequently Asked Questions

Find Quick Answers

What formats are supported?

Supports ESRI Shapefile components (.shp, .shx, .dbf) with optional .prj, or a ZIP archive containing these files. GeoJSON export is available as an alternative.

How is data processed?

All editing operations are performed in-browser. Exports produce a new shapefile ZIP or GeoJSON that contains your edits; files are not uploaded to a public server unless you opt to.

Can I reproject data?

Yes. You can select a target CRS and apply a coordinate transformation during export, preserving or converting units as defined by the target projection.

Are there limitations?

Large shapefiles may require longer processing times or chunked reads; advanced GIS operations beyond basic editing and reprojection are not included in this tool.
