Step by step

How It Works

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

Technical note

How BSQ and ICO differ in practice

BSQ carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. ICO 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 BSQ original if the data still has to go back into a GIS. ICO stores a limited palette rather than full colour, so the conversion has to reduce the number of distinct colours. Photographic content shows this as banding, while flat graphics and icons usually survive it untouched.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to ICO 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.

Working in a print studio means constantly juggling obscure file formats. I used to waste hours Googling converters or installing random software — until reaConverter became my Swiss Army knife. Install it once, and you're set forever. No internet? No problem!
