File Conversion
Convert FGB to SQLite online
Convert FlatGeobuf — a fast, streamable binary format built for large datasets — into SpatiaLite / SQLite, which is a single-file spatial database. Drop your FGB file below, SQLite 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 SQLite 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 SQLite 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 SQLite at a glance
| FGB | SQLite | |
|---|---|---|
| Typical use | Large datasets streamed to web maps; cloud-native data pipelines | Single-file spatial database (SpatiaLite) for analysis and apps |
| Size on disk | Compact binary with a built-in spatial index | Compact single file; multiple tables/layers |
| Attribute support | Full attribute tables | Full SQL types — query with plain SQL |
| Software support | GDAL/QGIS, plus web libraries via the flatgeobuf JS package | GDAL, QGIS, plus any SQLite tooling |
| Web-friendliness | Excellent — streams over plain HTTP range requests | Not web-native — convert for the browser |
Other ways to convert FGB to SQLite
You don't need an online tool for this. If you have GDAL installed, one command does it:
ogr2ogr -f "SQLite" output.sqlite input.fgbIn QGIS (free): open your FGB via Layer → Add Layer, then right-click the layer → Export → Save Features As… and pick SQLite 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 SQLite: frequently asked questions
Is the FGB to SQLite 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-SQLite 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 SQLite result and it's yours to keep.
What does the SQLite output contain?
You get a clean SpatiaLite / SQLite file with your geometry and attributes preserved, ready to open in the tools that read SQLite.
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.
How do I open the SQLite output?
The result is a SpatiaLite-compatible database: drag it into QGIS to see the layer, or query it with any SQLite client — attributes are regular columns you can filter with SQL.
Can I convert SQLite back to FGB?
Yes — use our SQLite to FGB converter for the reverse direction. MapGO supports conversions in both directions between these formats.
