GIS File Preview

Drag & drop any GIS file to visualize it on an interactive map. Parsed entirely in your browser — no data is ever uploaded or stored. Click features to inspect their attributes.

How It Works

Drop Your File

Drag a GeoJSON, KML, GPX, Shapefile ZIP, or TopoJSON file onto the map, or click to browse. Supported up to 50 MB.

In-Browser Parsing

Your file is parsed locally using JavaScript libraries. Nothing is sent to a server — all processing stays in your browser tab.

Explore the Map
