How It Works

reaConverter offers the fastest, simplest solution for converting your GTIFF files into DCM without GIS software - all files processed on your PC for maximum privacy and speed.

Technical note

GTIFF to DCM: what carries over and what does not

GTIFF can carry an alpha channel and DCM cannot. Transparent areas are composited onto a solid background during conversion, so pick that background colour deliberately: white is the default, and it is rarely the right choice for a logo that will sit on a dark page.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to DCM 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.

Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch.
