Technical note

What changes when you convert GFF to BMP

GFF carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. BMP has nowhere to record any of that. The picture transfers intact, the location does not, so the output cannot be dropped onto a map afterwards without being placed by hand. Keep the GFF original if the data still has to go back into a GIS. GFF carries 32 bits per channel and BMP carries 8, 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 an 8-bit format only at the very end.

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 GFF 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.
