What is a .PMTiles file?
PMTiles packs an entire map tileset into one file that can be served with no backend.
- Did you know
- PMTiles lets a whole interactive map be hosted from a single static file.
- PMTiles was created by Brandon Liu of Protomaps as a cloud-optimised, serverless alternative to the SQLite-based MBTiles format.
- A reader can fetch any tile from a PMTiles archive over plain HTTP range requests, needing at most two requests whatever the file’s size.
- What Analyser reads
- Inspect geospatial and GIS files without a map: TopoJSON, OpenStreetMap XML, Esri Shapefile siblings (SHP/SHX/DBF/PRJ/CPG), world files, GML, NMEA GPS logs, IGC flight logs, MapInfo TAB/MIF, GDAL VRT, PMTiles, DTED terrain, Esri ASCII grids and SRTM .hgt - surfacing CRS/EPSG, feature/record counts, bounding boxes and elevation ranges.

- Depth of analysis
- .PMTiles is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .PMTiles file
- Drag a .PMTiles file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
