Convert GSB to STEP

Online GIS converters cap file size and need an upload. reaConverter converts GSB to STEP locally, whatever the size of the dataset.

Got a folder full of GSB files? reaConverter batch converts them to STEP in minutes, not hours. Local processing means instant results, even with thousands of files. Works without QGIS or ArcGIS, so GIS data can be converted on any office PC.

How to Convert Multiple .gsb Files to .step?

1. Download and Install reaConverter

reaConverter is a standalone Windows app — download, install, and start converting GSB files in under two minutes.

2. Load your GSB files

Add your GSB files to reaConverter. Whether it's a handful or an entire archive, the batch engine processes them efficiently.

3. Select STEP as output format

Pick STEP as the output format. If the data is going back into a GIS, choose a format that keeps coordinates and attributes; JPG, PNG and PDF suit maps for reports and slides.

Step by step

How It Works

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

Technical note

Before you convert GSB to STEP

GSB is made of pixels and STEP 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 a STEP container.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to STEP 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.

reaConverter has been a huge time-saver for our team. We regularly work with CAD models in STEP format, and converting them to images or other file types used to be a hassle. With reaConverter, the process is fast, accurate, and incredibly easy to set up. The batch conversion feature is especially useful when handling large projects. Highly recommended for anyone dealing with STEP files on a regular basis.
