File Conversion
Convert GPKG to KML online
Convert GeoPackage — the modern OGC SQLite-based container that stores multiple layers in a single file and is replacing the shapefile — into Keyhole Markup Language (KML), which is the Google Earth and Google Maps format. Drop your GPKG file below, KML is already selected as the output, and download the result. Everything runs in your browser and the cloud; you never install anything.

Drag and drop it into the converter below — no account needed to start.

MapGO detects the format and produces your download in seconds.

Why convert GPKG to KML with MapGO?
Most online converters take one file and hand back one file. MapGO is built on a real geospatial engine, so a single upload can do more:
- Several outputs in one upload — tick KML and any other formats you need; every selected format is delivered from the same file.
- Files up to 5 GB — far beyond the browser-based converters that choke past a few hundred megabytes.
- Reproject while you convert — set a source and target EPSG code and the coordinate system is changed during the conversion, no second tool needed.
- Private by default — files are deleted automatically after 48 hours.
GPKG vs KML at a glance
| GPKG | KML | |
|---|---|---|
| Typical use | The modern default for storing and exchanging GIS layers (QGIS standard) | Google Earth / Google My Maps visualisation and sharing placemarks |
| Size on disk | Compact single .gpkg file; many layers in one database | Verbose XML; the zipped KMZ variant shrinks it considerably |
| Attribute support | Full database types, long column names, spatial indexes | Styling-first — data lives in ExtendedData and is easy to lose |
| Software support | QGIS, ArcGIS Pro, GDAL — all current GIS software | Google Earth/Maps and most GIS tools |
| Web-friendliness | Not web-native — convert to GeoJSON or FlatGeobuf for the browser | Good inside the Google ecosystem; niche elsewhere |
Other ways to convert GPKG to KML
You don't need an online tool for this. If you have GDAL installed, one command does it:
ogr2ogr -f "KML" output.kml input.gpkgIn QGIS (free): open your GPKG via Layer → Add Layer, then right-click the layer → Export → Save Features As… and pick KML as the format.
The MapGO converter above is for when you don't want to install anything, need to convert to several formats at once, or are handling files too large for a desktop machine — drop the file and download the result.
GPKG to KML: frequently asked questions
Is the GPKG to KML converter free?
Yes — new accounts get free conversion credits to start, and every paid plan converts unlimited files within its size limit. There is nothing to install; the whole GPKG-to-KML conversion runs in the cloud.
Is my data kept private?
Conversion is fully automated and your file is never shared. Files are deleted automatically after 48 hours. Download your KML result and it's yours to keep.
What does the KML output contain?
You get a clean Keyhole Markup Language (KML) file with your geometry and attributes preserved, ready to open in the tools that read KML.
My GeoPackage contains several layers — which one gets converted?
MapGO converts the first vector layer in the file. If you need a different layer, export it to its own GeoPackage in QGIS (right-click the layer → Export) and upload that — multi-layer selection is on the roadmap.
Will my layer styling show up in Google Earth?
Geometry and attributes convert; symbology does not, because every format stores styling differently. Google Earth applies its default placemark style — restyle inside Google Earth after opening the file.
Can I convert KML back to GPKG?
Yes — use our KML to GPKG converter for the reverse direction. MapGO supports conversions in both directions between these formats.
