Specialized Tools
View and convert formats that used to require specialist software: CAD, GIS, 3D, scientific data and more.
3 tools
3D Model Viewer
Open 3D models in STL, GLB (glTF), OBJ, FBX or PLY right in your browser, with no 3D software. Rotate them, check the size, volume and holes, and save the current view as a PNG or convert the model to GLB, STL or OBJ. Your files stay on your device.
GeoJSON Studio
Open GeoJSON, TopoJSON, KML, GPX, CSV or WKT, draw the coordinates on a simple plain map, and check them against RFC 7946. You can also convert between formats and measure area and length on a sphere. Files are never sent to a server.
GIS Coordinate Tool
Convert latitude and longitude (decimal, DMS, degrees-minutes), the old Tokyo Datum, Japan plane rectangular coordinates, UTM, Web Mercator, regional mesh codes and geohash. Convert whole CSV or Excel columns at once, and calculate the distance and azimuth between two points.
