GeoPackage is an open standard defined by OGC, implemented on SQLite database technology. It is a single container file that can simultaneously store vector features, raster imagery, attribute tables, and map tiles. GeoPackage requires no database server and can be used directly on mobile devices and desktop applications, making it an ideal choice for modern GIS data exchange.
GML (Geography Markup Language) is an XML-based geospatial data encoding standard defined by the Open Geospatial Consortium (OGC). GML provides rich geospatial data modeling capabilities, supporting complex geometry types, topology, coordinate reference systems, and spatiotemporal data. GML is widely used in European and government sectors, often for national spatial data infrastructures (SDI).
Converting GeoPackage to GML is one of the most common workflows in GIS. GeoPackage data usually comes from desktop GIS software, government open-data portals, or data exchange with partners, while GML is what modern tools, web maps, and platforms expect. This converter bridges the two: it reads your GeoPackage files, keeps geometry and attributes intact, and writes clean GML output — entirely in your browser, so your data never leaves your device.
No. The conversion runs entirely in your browser using WebAssembly — your files never leave your device.
Yes, completely free with no sign-up and no usage limits.
By default the output keeps the source coordinate system. If your GeoPackage file uses a projected CRS (like UTM), you can search any EPSG coordinate system by keyword or code and reproject in one step. Note: output formats that require WGS84 by specification (KML, KMZ, GPX) always reproject to WGS84 automatically.
Yes — drop several GeoPackage files at once and each one produces its own GML output.
Upload your GeoPackage file — drag and drop it onto the page, or browse from your device. You can add several files at once for batch conversion.
The conversion runs automatically in your browser. No upload, no server — your data stays on your device the entire time.
Download the GML file. Each input produces its own output, ready to use in your GIS, web map, or archive.
