File Conversion
Convert SHP to FGB online
Convert Esri Shapefile — the Esri format used by ArcGIS and QGIS — really a set of files (.shp, .dbf, .prj, …) bundled in a .zip — into FlatGeobuf, which is a fast, streamable binary format built for large datasets. Drop your SHP file below, FGB is already selected as the output, and download the result. Everything runs in your browser and the cloud; you never install anything.

Why convert SHP to FGB 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 FGB 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.
SHP vs FGB at a glance
| SHP | FGB | |
|---|---|---|
| Typical use | Desktop GIS in ArcGIS/QGIS; the long-time industry exchange format | Large datasets streamed to web maps; cloud-native data pipelines |
| Size on disk | Large — several sidecar files, no compression, 2 GB per-file cap | Compact binary with a built-in spatial index |
| Attribute support | Limited: column names max 10 characters, no lists or nesting | Full attribute tables |
| Software support | Universal in GIS software; web libraries can’t read it directly | GDAL/QGIS, plus web libraries via the flatgeobuf JS package |
| Web-friendliness | Poor — must be converted before use in a web map | Excellent — streams over plain HTTP range requests |
Other ways to convert SHP to FGB
You don't need an online tool for this. If you have GDAL installed, one command does it:
ogr2ogr -f "FlatGeobuf" output.fgb input.shpIn QGIS (free): open your SHP via Layer → Add Layer, then right-click the layer → Export → Save Features As… and pick FGB 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.
SHP to FGB: frequently asked questions
Is the SHP to FGB 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 SHP-to-FGB 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 FGB result and it's yours to keep.
How do I upload a shapefile?
A shapefile is several files that belong together (.shp, .shx, .dbf, .prj). Zip them into a single .zip and upload that — MapGO reads all the parts and warns you if a required piece (like the .dbf) is missing.
Why are some of my column names cut off after converting a shapefile?
The shapefile’s .dbf table limits column names to 10 characters, so longer names were already truncated when the shapefile was created. The conversion preserves exactly what the shapefile stores — rename the columns in your GIS before exporting if you need the full names back.
What is FlatGeobuf actually good for?
It is a binary format with a built-in spatial index that web maps can stream over plain HTTP — the browser fetches only the features in view, no tile server required. Leaflet, MapLibre and OpenLayers read it via the flatgeobuf JavaScript package.
Can I convert FGB back to SHP?
Yes — use our FGB to SHP converter for the reverse direction. MapGO supports conversions in both directions between these formats.
