Convert GPKG to GeoJSON online
Convert GeoPackage — the modern OGC SQLite-based container that stores multiple layers in a single file and is replacing the shapefile — into GeoJSON, which is the open, web-native JSON format read by Leaflet, Mapbox and virtually every modern GIS tool. Drop your GPKG file below, GeoJSON is already selected as the output, and download the result. Everything runs in your browser and the cloud; you never install anything.
Upload your file
Drag and drop it into the converter below. A free account comes with three welcome conversions.

MapGO detects the format and produces your download in seconds.

Why convert GPKG to GeoJSON 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 GeoJSON 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 GeoJSON at a glance
| GPKG | GeoJSON | |
|---|---|---|
| Typical use | The modern default for storing and exchanging GIS layers (QGIS standard) | Web maps and APIs (Leaflet, Mapbox, D3); human-readable data in git |
| Size on disk | Compact single .gpkg file; many layers in one database | Verbose plain text — the largest of the common formats, but gzips well |
| Attribute support | Full database types, long column names, spatial indexes | Flexible JSON properties — nesting and arrays allowed |
| Software support | QGIS, ArcGIS Pro, GDAL — all current GIS software | Every modern GIS tool and every web mapping library |
| Web-friendliness | Not web-native — convert to GeoJSON or FlatGeobuf for the browser | Excellent — the native format of web mapping |
Other ways to convert GPKG to GeoJSON
You don't need an online tool for this. If you have GDAL installed, one command does it.
In QGIS (free): open your GPKG via Layer → Add Layer, then right-click the layer → Export → Save Features As… and pick GeoJSON 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.

Is the GPKG to GeoJSON converter free?
Partly. Every new account gets three welcome conversions for free, so you can try GPKG to GeoJSON without paying. After that, you can either buy a credit pack and pay per conversion, or take a subscription, which gives you unlimited conversions within the plan's file-size limit. There is nothing to install; the whole 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 GeoJSON result and it's yours to keep.
What does the GeoJSON output contain?
You get a clean GeoJSON file with your geometry and attributes preserved, ready to open in the tools that read GeoJSON.
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.
Which coordinate system will the GeoJSON output use?
By default the output keeps your source coordinate system; pick EPSG:4326 (WGS84) as the target if you want spec-standard GeoJSON that works immediately in Leaflet, Mapbox and other web libraries. MapGO reprojects during the conversion — no separate step needed.
Can I convert GeoJSON back to GPKG?
Yes — use our GeoJSON to GPKG converter for the reverse direction. MapGO supports conversions in both directions between these formats.
