Step by step

How It Works

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

Technical note

How HFZ and AI differ in practice

HFZ 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. How good the result is depends almost entirely on the HFZ going in. Clean line art, a logo or a drawing scanned at 300 dpi or more traces into geometry you can work with. A photograph does not: continuous tone has no contours to follow, so tracing it produces thousands of tiny shapes and a file nobody can edit. Scan or export at the highest resolution available, and prefer a lossless original, because compression artefacts along an edge become ripples in the traced path.

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 HFZ 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.

Client demanded PNGs but sent AI files ‘because you have Adobe, right?’ Jokes on them—reaConverter handled it while I sipped my coffee.

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!
