Frequently asked questions

How do I open a .geojson file?

Drag your .geojson or .json file onto the drop zone above, or click to browse for it. The file is parsed in your browser and every feature is drawn on the map immediately. Nothing is uploaded.

Is my GeoJSON file uploaded to a server?

No. Parsing and rendering happen entirely inside your browser using JavaScript. Your file never leaves your device, which makes this safe for confidential or proprietary data.

What geometry types are supported?

All RFC 7946 geometry types: Point, MultiPoint, LineString, MultiLineString, Polygon, MultiPolygon and GeometryCollection, in both Feature and FeatureCollection form.

Can I see the properties of each feature?

Yes. Click any feature on the map to open a popup listing its properties. The summary above the map also reports the total feature count and the geometry types present.

Is there a file size limit?

Files up to about 30MB work well. Large files are drawn on a canvas renderer so that even datasets with tens of thousands of features stay responsive.
