GeoPackage to PMTiles

GeoPackage to PMTiles Converter Online | GeoDataViewer

Quick answer: Convert GPKG (GeoPackage) to PMTiles online for free. Open your GPKG (GeoPackage) data, inspect the map preview, and download PMTiles output locally in your browser — no upload required. GeoPackage is an OGC-standard SQLite-based container that stores vector data, attributes, and related geospatial tables inside a single portable file.

Before converting GeoPackage to PMTiles

Prepare the input

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

Know what you download

PMTiles 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 GeoPackage to PMTiles 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.

Prepare your file and check the result

Before opening

Choose a vector GeoPackage. A .gpkg may contain several tables or raster tiles, so identify the feature layer you need.

Before sharing or converting

Review the loaded layers and their attributes. Compare against the source layer list before treating the preview as the entire package.

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.

Conversion steps

How to convert GPKG (GeoPackage) to PMTiles online

1. Add your GPKG (GeoPackage) 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 PMTiles

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

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 PMTiles?

Teams commonly convert GeoPackage into PMTiles when they need single-file cloud hosting of tiled vector data.

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.
PMTiles is attractive when you want to publish tiles from object storage with minimal server overhead.
It works well for browser delivery because readers can fetch only the byte ranges they need.

FAQ

Frequently asked questions about GeoPackage to PMTiles

What do I need before converting GeoPackage to PMTiles?

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

What exactly is in the PMTiles download?

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

How large a GeoPackage 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 GeoPackage 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.
