File Geodatabase to MBTiles

FileGDB to MBTiles Converter Online | GeoDataViewer

Quick answer: Convert FileGDB to MBTiles online for free. Open your FileGDB data, inspect the map preview, and download MBTiles output locally in your browser — no upload required. File Geodatabase is an Esri geodatabase storage format that organizes datasets as a folder-based database instead of a single portable file.

Before converting File Geodatabase to MBTiles

Prepare the input

Choose a complete File Geodatabase dataset (.zip, .gdbtable, .gdbtablx, .gdbindexes, .atx). Keep required sidecar files together and check the source coordinate reference system.

Know what you download

MBTiles 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 File Geodatabase to MBTiles 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 File Geodatabase?

File Geodatabase is an Esri geodatabase storage format that organizes datasets as a folder-based database instead of a single portable file.

FileGDB is widely used in ArcGIS environments because it can hold multiple feature classes, tables, and related content inside one geodatabase directory.

That structure is powerful inside Esri workflows, but it is less convenient than single-file formats for email, versioning, web uploads, and cross-platform sharing.

Common Workflows

Common use cases

Utility, government, environmental, and infrastructure projects built around ArcGIS desktop workflows.
Folder-based delivery of multiple feature classes and reference tables.
Intermediate storage before data is repackaged for portals, vendors, or web products.

Ecosystem

Where you will encounter it

ArcGIS desktop and geodatabase-centered enterprise workflows.
Multi-layer project packaging in Esri-heavy organizations.
Vendor deliveries where FileGDB is an accepted handoff format.

Strengths

Why teams choose File Geodatabase

Can hold multiple layers and related tables in one geodatabase structure.
Strong fit for ArcGIS workflows and geodatabase-oriented data management.
More expressive than simple flat exchange formats when the project is multi-layer.

Limitations

Where File Geodatabase gets awkward

FileGDB is a folder dataset, so it often needs zipping before transfer or browser upload.
Non-Esri workflows frequently prefer a more neutral or simpler delivery format.
The structure is less convenient for quick manual inspection than text or single-file containers.

Conversion steps

How to convert FileGDB to MBTiles online

1. Add your FileGDB 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 MBTiles

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

File Structure

Common file extensions and sidecar files

.gdb folder

Main geodatabase directory that contains tables, indexes, and supporting metadata files.

.gdbtable

Internal storage files used for tables and feature classes inside the geodatabase.

.gdbtablx

Internal index files that support geodatabase table access.

zipped .gdb folder

Common way to move a FileGDB through email, browsers, and archive systems that expect one transferable package.

Conversion Rationale

Why convert File Geodatabase to MBTiles?

Teams commonly convert File Geodatabase into MBTiles when they need a portable SQLite tile archive for offline distribution.

Teams convert FileGDB when data needs to move outside ArcGIS into open, web-friendly, or single-file formats.
Conversion is also common when recipients only need one layer rather than a full geodatabase folder structure.
MBTiles packages tiled content into one file that is easy to ship to mobile, desktop, or field environments.
It is a common target when the output is meant for cached viewing rather than direct feature editing.

FAQ

Frequently asked questions about File Geodatabase to MBTiles

What do I need before converting File Geodatabase to MBTiles?

Choose a complete File Geodatabase dataset (.zip, .gdbtable, .gdbtablx, .gdbindexes, .atx). Keep required sidecar files together and check the source coordinate reference system.

What exactly is in the MBTiles download?

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

How large a File Geodatabase 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 File Geodatabase 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.
