Step by step

How It Works

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

Technical note

How PEF and MIF differ in practice

PEF files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to MIF bakes those decisions into the pixels, and highlight recovery is no longer available afterwards. Set white balance and exposure before the run rather than after.

Map Data Workflow

Bring files into a GIS

reaConverter takes PEF files to MIF a folder at a time, on your own PC, ready to be added to a GIS project and georeferenced there.

  • Convert a whole folder to MIF in one pass
  • Apply the same settings to every file in the batch
  • 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.
