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

Why convert KML to GPKG 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 GPKG 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.
KML vs GPKG at a glance
| KML | GPKG | |
|---|---|---|
| Typical use | Google Earth / Google My Maps visualisation and sharing placemarks | The modern default for storing and exchanging GIS layers (QGIS standard) |
| Size on disk | Verbose XML; the zipped KMZ variant shrinks it considerably | Compact single .gpkg file; many layers in one database |
| Attribute support | Styling-first — data lives in ExtendedData and is easy to lose | Full database types, long column names, spatial indexes |
| Software support | Google Earth/Maps and most GIS tools | QGIS, ArcGIS Pro, GDAL — all current GIS software |
| Web-friendliness | Good inside the Google ecosystem; niche elsewhere | Not web-native — convert to GeoJSON or FlatGeobuf for the browser |
Other ways to convert KML to GPKG
You don't need an online tool for this. If you have GDAL installed, one command does it:
ogr2ogr -f "GPKG" output.gpkg input.kmlIn QGIS (free): open your KML via Layer → Add Layer, then right-click the layer → Export → Save Features As… and pick GPKG 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.
KML to GPKG: frequently asked questions
Is the KML to GPKG 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 KML-to-GPKG 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 GPKG result and it's yours to keep.
What does the GPKG output contain?
You get a clean GeoPackage file with your geometry and attributes preserved, ready to open in the tools that read GPKG.
What happens to the attributes stored in my KML?
KML keeps attribute data in ExtendedData elements (and sometimes in free-text descriptions). Structured ExtendedData fields are mapped to real attribute columns in the output; icons and styling are display settings rather than data, so they don’t carry over.
Why convert to GeoPackage instead of shapefile?
GeoPackage is one file instead of five, has no 10-character column-name limit, no 2 GB cap, and stores multiple layers with spatial indexes. QGIS uses it as the default format — it is the recommended target unless a legacy tool forces shapefiles.
Can I convert GPKG back to KML?
Yes — use our GPKG to KML converter for the reverse direction. MapGO supports conversions in both directions between these formats.
