Technical note

How PMTILES and FITS differ in practice

PMTILES is a tile set: the same map cut into small squares, usually 256 or 512 pixels across, at a range of zoom levels, each level holding four times as many tiles as the one above it. FITS holds one flat picture, so the zoom level is the decisive choice. A low level gives a compact overview of the whole area, while the deepest levels of a city or a country run to millions of tiles and an image far larger than any viewer will open. PMTILES describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the FITS afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.

Map Data Workflow

Turn GIS data into something anyone can open

A map saved as FITS opens on any computer and any phone. reaConverter produces those from PMTILES in batch, entirely offline.

  • Render every file in a folder to FITS with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.
