Step by step

How It Works

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

Technical note

How NSF and STP differ in practice

NSF is made of pixels and STP is a geometry format, so the two describe shape in fundamentally different ways. Check the result before sending it downstream: what matters is whether the output contains usable geometry or a picture placed inside an STP container.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to STP 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.
