Step by step

How It Works

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

Technical note

How CUB and AVIF differ in practice

CUB carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. AVIF has nowhere to record any of that. The picture transfers intact, the location does not, so the output cannot be dropped onto a map afterwards without being placed by hand. Keep the CUB original if the data still has to go back into a GIS. CUB stores pixels without compression loss and AVIF does not, so this is a one-way step. Choose a high quality setting, and avoid converting the same file back and forth, because each pass compounds the artefacts.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to AVIF 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.

Twitch thumbnails keep saving as AVIF and my editing software freaks out. reaConverter swaps them to JPEG instantly. Now I can actually post my ‘🔥HOT TAKES🔥’ without crying over file errors.

Google Photos auto-saved my pics as AVIF files that won’t open anywhere. reaConverter rescued 3 years of memories AND kept the quality. Take that, ‘innovation’!
