geo.io is a browser-based editor for creating, viewing, and sharing spatial map data, originally built by Mapbox in 2013 and overhauled in 2026 with a modern React/TypeScript codebase based on Placemark Play. It supports drawing geometries on an interactive Mapbox GL map and importing/exporting GeoJSON, KML, CSV, and Shapefile formats.
Use cases
- draw polygons on a map and export as geo
- convert kml to geo in the browser
- quickly visualize a geo file
- edit feature properties of spatial data
- create points lines and polygons for a mapping project
- share map data with a colleague
- convert csv coordinates to geo
When to choose
- you need a fast, no-install browser tool to create or edit GeoJSON
- you want to convert between GeoJSON, KML, CSV, and Shapefile without GIS software
- you need to visually inspect or share small spatial datasets
When to avoid
- you need heavy-duty desktop GIS analysis like QGIS or ArcGIS
- you need offline editing or large-dataset processing
- you require programmatic headless GeoJSON manipulation (use a library instead)
