Inspect, convert, measure and clean geospatial data — privately, in your browser.
The Mixadù GIS Toolkit is a searchable set of 20 lightweight geospatial tools — a universal map viewer, coordinate converter (UTM, MGRS, State Plane, Web Mercator), CRS detector, GeoJSON/KML/KMZ/GPX viewers, CSV mapper, geometry validator, measurement and buffer tools, format converter, quality checks, elevation profiles and PDF report generator. It reads GeoJSON, KML, KMZ, GPX, CSV, WKT, TopoJSON and zipped Shapefiles, and exports GeoJSON, CSV, KML, GPX, WKT and PNG/PDF maps. Every file is processed locally in your browser — nothing is ever uploaded.
- View GeoJSON, KML, KMZ, GPX, CSV, WKT, TopoJSON and zipped Shapefiles on an interactive map
- Convert coordinates between Lat/Lon, UTM, MGRS, State Plane and Web Mercator
- Measure distance, area, bearing; buffer, simplify and validate geometry
- Export GeoJSON, CSV, KML, GPX, WKT and presentation-ready PNG/PDF maps — all local, no uploads
Frequently asked questions
Are my files uploaded anywhere?
No. Every file is parsed and processed locally in your browser; nothing is sent to a server.
Which formats can it read?
GeoJSON, KML, KMZ, GPX, CSV, WKT, TopoJSON and zipped Shapefiles (.shp/.dbf/.prj).
Can it convert coordinates?
Yes — between latitude/longitude, DMS, UTM, MGRS, Web Mercator, and State Plane or custom projections you supply parameters for.
Can I export a map as PDF or image?
Yes. The Map Snapshot and Report Generator export presentation-ready PNG and PDF maps with title, legend, north arrow, scale bar and attribution.
Is the GIS Toolkit free?
Yes, all 20 tools are free with no login or sign-up.
