How It Works

Technical note

How PMTILES and BMP 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. BMP 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. A PMTILES file holds geometry and an attribute table, and nothing at all about appearance. Colours, line weights, fills and labels are properties of the GIS project rather than of the file, which is why the same PMTILES looks different in every program that opens it. The BMP render therefore falls back on defaults and will not match the styled map you see in QGIS or ArcGIS. Expect a clean drawing of the geometry rather than a finished cartographic product.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to BMP with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Stamp a text watermark, such as a project name or a date, on every image
  • 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.

This online converter works perfectly for small batches of files. I occasionally need to convert BMP to JPG, and it doesn't make sense to install software for such simple tasks. It's much easier to just visit the site, click a couple buttons, and get the same quality result in seconds.
