FlatGeobuf Converter

Convert FlatGeobuf to GeoJSON, GeoPackage, or a contained Shapefile ZIP, and create FlatGeobuf from supported vector files.

Choose a contained vector file to begin.

Pełne dane, wyraźne niepowodzenia

Every feature in the selected layer is written or the conversion fails. Shapefile field-name, field-type, geometry, and sidecar limits are checked instead of silently truncating data.

dane o prywatnym miejscu

Only upload coordinates and attributes you have authority to process. Filenames, layer names, field names, exact CRS codes, coordinates, bounds, and attribute values are excluded from logs and analytics.

Nie odległe korzystanie

The worker processes only the uploaded file. It does not fetch map tiles, remote schemas, URLs, virtual filesystems, or external datasets.

Formatowe

GeoPackage and FlatGeobuf preserve richer schemas than Shapefile. GeoJSON output uses WGS 84; choose EPSG:4326 explicitly when the source uses another CRS.
