PMTiles is a single-file archive format for pyramids of map tiles that can be hosted on commodity static storage like S3 and accessed via HTTP Range Requests. It includes libraries (JavaScript, Python, Go, OpenLayers) and a CLI for creating, converting, extracting, and serving tile archives without a custom tile server.

Use cases

  • host map tiles on S3 without a tile server
  • convert mbtiles to pmtiles
  • extract a regional subset of a planet-wide basemap
  • serve vector tiles serverlessly from cloud storage
  • display pmtiles archives in MapLibre or Leaflet
  • reduce map hosting costs by eliminating tile backends

When to choose

  • you want low-cost, zero-maintenance map hosting on static object storage
  • you need a single-file tile archive instead of millions of tile files
  • you want to avoid running a tile server or paying a third-party tile provider

When to avoid

  • you need real-time tile generation or frequent tile updates
  • your storage or CDN does not support HTTP Range Requests
  • you need features of a full tile server like dynamic styling or on-the-fly reprojection
