Step by step

How It Works

reaConverter offers the fastest, simplest solution for converting your 000 files into FITS without GIS software - all files processed on your PC for maximum privacy and speed.

Technical note

000 to FITS: what carries over and what does not

A 000 file holds geometry and an attribute table, and nothing at all about appearance. Colours, line weights, fills and labels are properties of the GIS project rather than of the file, which is why the same 000 looks different in every program that opens it. The FITS render therefore falls back on defaults and will not match the styled map you see in QGIS or ArcGIS. Expect a clean drawing of the geometry rather than a finished cartographic product. 000 describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the FITS afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see 000 data has GIS software. reaConverter renders it to FITS for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to FITS 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.
