MBTiles to FlatGeobuf

MBTiles to FlatGeobuf Converter Online | GeoDataViewer

Quick answer: Convert MBTiles to FlatGeobuf online for free. Open your MBTiles data, inspect the map preview, and download FlatGeobuf output locally in your browser — no upload required. MBTiles is a SQLite-based tile archive format that stores tiled map content in one portable file for offline and packaged distribution workflows.

Before converting MBTiles to FlatGeobuf

Prepare the input

Choose a complete MBTiles dataset (.mbtiles). Keep required sidecar files together and check the source coordinate reference system.

Know what you download

FlatGeobuf output is downloaded as a file, or ZIP when the driver generates sidecars. Compare the result against the source before sharing.

Limits and troubleshooting

Converting MBTiles to FlatGeobuf can change field types, metadata and presentation. A successful download does not prove every source element survived.
Browser memory varies by device. There is no guaranteed unlimited file size; split large datasets or use a desktop GIS when memory or WASM initialization fails.

If something goes wrong

Empty or partial preview: confirm the source contains supported vector geometry and compare the source layers with the preview.
Wrong continent or distorted geometry: inspect the source CRS, axis order and a known location. Valid syntax alone does not guarantee valid placement.
Conversion cannot start: reload while online so processing libraries and WebAssembly can load, then retry a smaller known-good sample. File contents are still processed locally.
Incomplete export: compare source/output counts, geometry families and key fields. Inspect warnings and keep the original file.

Source Format Guide

What is MBTiles?

MBTiles is a SQLite-based tile archive format that stores tiled map content in one portable file for offline and packaged distribution workflows.

MBTiles became popular because it lets teams ship a tile dataset as one file instead of a directory of many small tiles, which is useful for mobile, desktop, and field deployments.

It works well when the objective is cached viewing or packaged delivery, but it is not the same thing as a canonical feature-editing dataset used for attribute cleanup and spatial QA.

Common Workflows

Common use cases

Offline field map packages and disconnected desktop environments.
Portable basemap delivery for mobile apps or kiosk-style deployments.
Archive handoff for tiled map products that are consumed as tiles instead of as editable features.

Ecosystem

Where you will encounter it

Offline mobile and field map delivery.
Tile packaging and archival workflows.
Desktop or embedded viewers that understand MBTiles.

Strengths

Why teams choose MBTiles

Single-file packaging is convenient for offline and portable use.
Familiar workflow in many mobile and packaged map delivery stacks.
SQLite container keeps tiles organized in a durable archive format.

Limitations

Where MBTiles gets awkward

MBTiles is focused on tile delivery, not general feature editing.
Attribute-rich analytical work usually requires conversion back into a feature-oriented format.
It is less transparent to inspect manually than text formats or ordinary spreadsheets.

Conversion steps

How to convert MBTiles to FlatGeobuf online

1. Add your MBTiles file

Drop the source data into the converter above. Keep any required sidecar files together when your dataset uses them.
2. Check the map preview

Inspect the geometry and attributes before exporting so you can spot missing layers or coordinate-system issues.
3. Download FlatGeobuf

Run the conversion and save the generated FlatGeobuf output directly from your browser. Your source file stays on your device.

File Structure

Common file extensions and sidecar files

.mbtiles

Main SQLite archive containing tile payloads and supporting metadata tables.

metadata table

Internal table that describes the archive, layer settings, and tile characteristics for readers.

Conversion Rationale

Why convert MBTiles to FlatGeobuf?

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

Teams convert MBTiles when they need feature-level analysis, editing, or export instead of a packaged tile archive.
They also convert MBTiles into PMTiles or raw MVT flows when a different tile hosting strategy is required.
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 MBTiles to FlatGeobuf

What do I need before converting MBTiles to FlatGeobuf?

Choose a complete MBTiles dataset (.mbtiles). Keep required sidecar files together and check the source coordinate reference system.

What exactly is in the FlatGeobuf download?

FlatGeobuf output is downloaded as a file, or ZIP when the driver generates sidecars. Compare the result against the source before sharing.

How large a MBTiles file can I convert?

The practical limit depends on browser memory, geometry complexity and the conversion driver. Start with a small sample. There is no guaranteed unlimited size and no cloud fallback or payment tier for large files.

Are my MBTiles files sent to a server?

File parsing and conversion run on your device. The page, WebAssembly and map basemaps can make network requests; choosing a file does not upload its contents. Load the required libraries before attempting offline work.
