PMTiles to GeoJSON

PMTiles to GeoJSON Converter Online | GeoDataViewer

Quick answer: Convert PMTiles to GeoJSON online for free. Open your PMTiles data, inspect the map preview, and download GeoJSON output locally in your browser — no upload required. PMTiles is a single-file tile archive format designed for cloud-friendly distribution of tiled map data with byte-range access.

Before converting PMTiles to GeoJSON

Prepare the input

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

Know what you download

GeoJSON output is a feature collection with geometry and readable attributes. Inspect the actual output coordinates before using it as a web-map layer.

Limits and troubleshooting
  • Converting PMTiles to GeoJSON can change field types, metadata and presentation. A successful download does not prove every source element survived.
  • Confirm WGS 84 longitude/latitude placement in the downloaded output. Missing source CRS cannot be inferred safely; use a desktop GIS to assign or reproject an unknown CRS.
  • 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 PMTiles?

PMTiles is a single-file tile archive format designed for cloud-friendly distribution of tiled map data with byte-range access.

PMTiles packages a full tile pyramid into one object, which makes it appealing for static hosting, object storage, and low-ops publication workflows.

Instead of relying on many small tile files, readers can request byte ranges from one archive, which simplifies deployment while keeping tile-driven rendering behavior.

Common Workflows

Common use cases

  • Static-cloud publication of vector basemaps and thematic tile layers.
  • Shipping tiled data to users who want one archive instead of many tile files.
  • Repackaging tile pyramids for simpler hosting and distribution.
Ecosystem

Where you will encounter it

  • Static hosting, CDN, and object storage delivery.
  • Browser tile readers and modern map publishing stacks.
  • Tile pipelines that want a portable single-file archive.
Strengths

Why teams choose PMTiles

  • Single-file tile archive is simpler to host and distribute than deep tile folder trees.
  • Byte-range access works well with cloud object storage and CDN delivery.
  • Good fit for modern low-infrastructure map publishing.
Limitations

Where PMTiles gets awkward

  • PMTiles is still a tile-delivery format, not a feature-editing workspace.
  • Some GIS users are less familiar with it than MBTiles or flat feature formats.
  • Analysts often need conversion before doing desktop review or attribute-heavy edits.
Conversion steps

How to convert PMTiles to GeoJSON online

  1. 1. Add your PMTiles file

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

  2. 2. Check the map preview

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

  3. 3. Download GeoJSON

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

File Structure

Common file extensions and sidecar files

.pmtiles
Main single-file PMTiles archive containing tile data and index structures.
internal tile index
Embedded index information that lets clients resolve which byte ranges to request.
Conversion Rationale

Why convert PMTiles to GeoJSON?

Teams commonly convert PMTiles into GeoJSON when they need a web-friendly format that is easy to inspect and debug.

  • Teams convert PMTiles when they need flat feature formats for editing or analysis instead of tiled delivery archives.
  • They also convert PMTiles into other tile containers when downstream systems already standardize on a different archive type.
  • GeoJSON is readable as plain text and widely supported in web mapping libraries and APIs.
  • It is a practical handoff format when you need to validate geometry and attributes quickly.
FAQ

Frequently asked questions about PMTiles to GeoJSON

What do I need before converting PMTiles to GeoJSON?

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

What exactly is in the GeoJSON download?

GeoJSON output is a feature collection with geometry and readable attributes. Inspect the actual output coordinates before using it as a web-map layer.

How large a PMTiles 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 PMTiles 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.

Can I use the output in Leaflet, MapLibre or Mapbox?

These libraries can read GeoJSON geometry and properties. Check that the actual output uses WGS 84 longitude, latitude and that required attributes survived. Add your web-map styling separately; KML styling is not a portable GeoJSON style specification.
