Convert FlatGeobuf to GeoPackage Online — Free & Instant
GeoPackage is the preferred format for multi-layer desktop GIS projects in QGIS and ArcGIS Pro. Converting FlatGeobuf to GeoPackage gives you a SQLite-based file with full spatial indexing and the ability to store multiple layers — useful when building a QGIS project from cloud-sourced FlatGeobuf data.

About FlatGeobuf
FlatGeobuf is a modern, high-performance binary format for geospatial vector data, designed for efficient streaming and cloud-native workflows. Based on FlatBuffers, it supports random access via HTTP range requests, making it ideal for serving large datasets directly from object storage like S3 without a tile server. FlatGeobuf is an OGC Community Standard and is supported by GDAL 3.1+, QGIS, Mapbox, and the GeoJSON ecosystem. Its compact binary encoding is significantly faster to parse than GeoJSON for large datasets.
Strengths
- +Extremely fast read/write — binary encoding
- +Supports HTTP range requests for cloud-native access
- +OGC Community Standard
- +Compact — much smaller than equivalent GeoJSON
About GeoPackage
GeoPackage (GPKG) is a modern, open standard format defined by the OGC that stores geospatial data in a single SQLite database file. It supports both vector and raster data, multiple layers per file, field name lengths up to 64 characters, and virtually any coordinate reference system. GeoPackage is endorsed by the OGC as the preferred replacement for Shapefile. It is supported by QGIS, ArcGIS Pro, GDAL, and PostGIS. Its SQLite base makes it portable and queryable without a server.
Strengths
- +Single file containing multiple layers
- +No field name length limit
- +Supports vector and raster in one file
- +SQLite-based — portable and queryable
Frequently asked questions
Q.Can I store multiple FlatGeobuf layers in one GeoPackage?
Not via this tool — Maparz converts one file at a time. For multi-layer GPKG, use QGIS or ogr2ogr with the -append flag.
