Convert GeoPackage to GML Online — Free & Instant
GeoPackage is the modern desktop GIS format, while GML is the OGC standard for data interchange via WFS services. Converting GPKG to GML prepares your QGIS or ArcGIS Pro project data for publication via OGC-compliant services or government data portals that mandate GML delivery.

About GeoPackage
GeoPackage (GPKG) is a modern, open standard format defined by the OGC that stores geospatial data in a single SQLite database file. It supports both vector and raster data, multiple layers per file, field name lengths up to 64 characters, and virtually any coordinate reference system. GeoPackage is endorsed by the OGC as the preferred replacement for Shapefile. It is supported by QGIS, ArcGIS Pro, GDAL, and PostGIS. Its SQLite base makes it portable and queryable without a server.
Strengths
- +Single file containing multiple layers
- +No field name length limit
- +Supports vector and raster in one file
- +SQLite-based — portable and queryable
About GML
Geography Markup Language (GML) is an XML-based OGC standard for encoding geographic features. It is the mandatory format for the EU INSPIRE directive and is commonly used in Web Feature Services (WFS) to deliver geospatial data over the web. GML files are highly interoperable across GIS platforms and are natively supported by GDAL, QGIS, ArcGIS, and GeoServer. GML can represent complex geometries, coordinate reference systems, and rich attribute schemas, making it the format of choice for authoritative government and infrastructure datasets.
Strengths
- +OGC standard — maximum interoperability
- +Mandatory for EU INSPIRE datasets
- +Supports complex geometries and CRS metadata
- +Native support in QGIS, ArcGIS, and GeoServer
Frequently asked questions
Q.Which layer is converted if the GeoPackage has multiple?
The first vector layer is converted. For specific layers, use QGIS or ogr2ogr locally.
