GeoPreview is a macOS app and Quick Look extension for previewing geospatial files directly in Finder.
Open a file in Finder to see a real map preview in the Preview Pane or Quick Look. Inspect attributes in a table, view geometry details, and check spatial metadata without launching a full GIS application.
GeoPreview supports many common GIS, CAD, and point-cloud formats used by developers, analysts, and mapping professionals.
