Convert FGB to GPKG online
Convert FlatGeobuf — a fast, streamable binary format built for large datasets — 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 FGB 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 FGB 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.
FGB vs GPKG at a glance
| FGB | GPKG | |
|---|---|---|
| Typical use | Large datasets streamed to web maps; cloud-native data pipelines | The modern default for storing and exchanging GIS layers (QGIS standard) |
| Size on disk | Compact binary with a built-in spatial index | Compact single .gpkg file; many layers in one database |
| Attribute support | Full attribute tables | Full database types, long column names, spatial indexes |
| Software support | GDAL/QGIS, plus web libraries via the flatgeobuf JS package | QGIS, ArcGIS Pro, GDAL — all current GIS software |
| Web-friendliness | Excellent — streams over plain HTTP range requests | Not web-native — convert to GeoJSON or FlatGeobuf for the browser |
Other ways to convert FGB 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.fgbIn QGIS (free): open your FGB 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.
FGB to GPKG: frequently asked questions
Is the FGB 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 FGB-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.
Why is the output so much bigger than my .fgb file?
FlatGeobuf is a compact binary format, while text formats like GeoJSON spell everything out — a size increase after conversion is normal and the data is identical. Gzip the text output when serving it and most of the difference disappears.
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 FGB?
Yes — use our GPKG to FGB converter for the reverse direction. MapGO supports conversions in both directions between these formats.
