Technical note

Before you convert MBTILES to CAL

MBTILES 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. CAL 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. MBTILES carries 8 bits per channel and CAL carries 1, so tonal steps get coarser during conversion. It shows up first in smooth gradients such as skies. If the result will be edited further, move to a 1-bit format only at the very end.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to CAL 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.
