FAQ
Hex or base64?
Paste either. You can also upload a .wkb file.
EWKB SRID handling?
If the WKB carries SRID we can output EWKT (toggleable). The SRID value is shown above the output.
What geometry types?
All standard OGC geometry types supported by wkx (Point, LineString, Polygon, Multi*, GeometryCollection).
Multiple geometries in one WKB?
If your WKB encodes MultiPoint/MultiLineString/MultiPolygon or a GeometryCollection, we output a single WKT geometry preserving that structure (and show the number of parts).
