About MapInfo TAB (TAB)

MapInfo Professional's native format — a bundle of .tab/.dat/.map/.id files.

Worth knowing: Keep the file bundle together (or zip it); one geometry type renders best.

The web-native vector format — plain JSON, readable by every mapping library and most modern GIS tools. RFC 7946 expects WGS84 coordinates.

Worth knowing: Text-based and verbose for large datasets; RFC 7946 deprecates non-WGS84 CRS metadata.

Drop your TAB files (all parts of the bundle, or a zip) above.
We read it locally with GDAL compiled to WebAssembly — nothing is uploaded.
Optionally pick an output coordinate system; official datum grids are applied automatically.
Download your GeoJSON result, with a transformation report showing exactly what was done.
