GeoJSON Visual Editor

Use this free, in-browser tool to edit GeoJSON features directly on a map. Nothing is uploaded—everything runs locally in your browser.

What you can do

• Open any valid GeoJSON (Feature, FeatureCollection, or bare geometries)
• Select one or more vertices (Shift+Click), drag to move
• Delete selected vertices (Delete/Backspace)
• Automatic cleanup: remove degenerate shapes as you delete
• Undo/Redo (Cmd/Ctrl+Z, Cmd/Ctrl+Shift+Z or Ctrl+Y)
• Export the updated GeoJSON

Tip: After loading, use the map controls to zoom and pan. Export ensures polygon rings are closed.
