What this conversion does

Input

GeoJSON

GeoJSON is a JSON format for geographic features: points, lines, polygons and their attributes.

Output

FlatGeobuf

FlatGeobuf is a binary, streamable vector format built for fast spatial reads, including over HTTP.

Use this converter when you have a GeoJSON file and the next step needs FlatGeobuf, for example fast streaming vector reads. The conversion is handled by a dedicated tool, so you do not have to install a desktop application to move a single file.

Limitations

  • Conversions run in the browser and share the memory your device gives the page. Very large files are better handled on a desktop or with a cloud task.

Frequently asked questions

Is GeoJSON to FlatGeobuf free?

Yes. This pair links to a converter that runs in your browser, and single-file conversions use a free daily allowance. No account is required to start, and you can register later for a larger allowance.

Do my files leave my device?

This pair links to a local browser converter, so the file is processed on your device and is not uploaded. Cloud processing, where a tool uses it, is labeled on the tool page and stores results only temporarily.

Can I convert several files at once?

Single-file conversion is available to everyone. Batch conversion is a paid capability, and cloud tasks have their own daily or monthly quotas. The pricing page lists the current limits.

What should I check after converting to FlatGeobuf?

Open it in a FlatGeobuf-aware viewer and confirm the spatial extent.
