How It Works

reaConverter offers the fastest, simplest solution for converting your NC4 files into AI without GIS software - all files processed on your PC for maximum privacy and speed.

Technical note

How NC4 and AI differ in practice

NC4 is made of pixels and AI stores geometry, so the conversion traces the image into paths. Once traced, the artwork scales to any size without softening, which is the point of the exercise. It is a reconstruction rather than the original drawing: curves are fitted to the pixel edges, so the cleaner and sharper the source, the closer the paths follow what the designer intended. Lettering in the image is traced as shapes, not recognised as text. Every character arrives as an outline that can be scaled and edited like any other geometry, but not retyped, restyled or searched, and no font is attached to it. Titles and callouts on a scanned drawing usually have to be typed again in the AI if they need to stay editable.

Map Data Workflow

Turn GIS data into something anyone can open

A map saved as AI opens on any computer and any phone. reaConverter produces those from NC4 in batch, entirely offline.

  • Render every file in a folder to AI 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.
