GeoPackage to FlatGeobuf Converter

GeoPackage is an OGC-standard SQLite-based container that stores vector data, attributes, and related geospatial tables inside a single portable file. Convert it to FlatGeobuf locally in your browser, inspect the map preview first, and export the generated files without uploading anything to a server.

Source Format Guide

What is GeoPackage?

GeoPackage is an OGC-standard SQLite-based container that stores vector data, attributes, and related geospatial tables inside a single portable file.

GeoPackage was designed to replace fragmented exchange patterns with a more modern, standards-based database file that travels easily between desktop, mobile, and offline environments.

Because it is based on SQLite, GeoPackage can support multiple tables and layers in one file while remaining easier to move and archive than folder-based geodatabases or sidecar-heavy formats.

Common Workflows

Common use cases

Sharing projects between desktop GIS users without bundling many sidecar files.
Offline data collection, review, or synchronization packages for field teams.
Delivering cleaned vector layers as a durable archive artifact rather than a loose folder tree.

Ecosystem

Where you will encounter it

Desktop GIS, mobile GIS, and offline field workflows.
Standards-oriented data delivery and archival packaging.
SQLite-friendly automation pipelines.

Strengths

Why teams choose GeoPackage

Single-file packaging is far easier to move and version than multi-file exchange formats.
SQLite foundation supports richer schema behavior and more organized storage.
OGC standardization makes GeoPackage a strong neutral delivery option.

Limitations

Where GeoPackage gets awkward

Some lightweight consumer tools still prefer simpler text or GPS-specific formats.
GeoPackage is less human-readable than text formats such as GeoJSON or CSV.
Tile-serving or browser streaming workflows may still favor dedicated tile formats.

File Structure

Common file extensions and sidecar files

.gpkg

Main SQLite-based GeoPackage file that can hold multiple vector tables and related metadata.

gpkg_contents and related tables

Internal metadata tables that describe what the package stores and how layers are organized.

Conversion Rationale

Why convert GeoPackage to FlatGeobuf?

Teams commonly convert GeoPackage into FlatGeobuf when they need faster read performance and lighter-weight distribution for static datasets.

Teams convert GeoPackage when they need a more lightweight web format, a GPS-specific exchange file, or a legacy format required by another toolchain.
GeoPackage is also commonly converted into tile outputs when the next step is browser rendering rather than feature editing.
FlatGeobuf is well suited to large download files that benefit from compact binary encoding.
It is a good target when you want a modern single-file alternative to older interchange formats.

FAQ

Frequently asked questions about GeoPackage

Why do many teams prefer GeoPackage over shapefile?

GeoPackage keeps data in one file, supports richer schemas, and avoids the fragility of sidecar-dependent packaging.

Is GeoPackage only for vector data?

No. The standard can also support tile-oriented content, although many workflows use it primarily for vector layers and tables.

Why convert GeoPackage to something else?

Conversion usually happens when the destination system expects a web-friendly JSON file, a GPS format, a tile archive, or a legacy exchange type.
