Technical note

Before you convert FGB to AVIF

An FGB 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 FGB looks different in every program that opens it. The AVIF 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. FGB coordinates are positions on the earth, tied to a stated reference system, and each feature carries its own row of attributes. AVIF is a picture: the coordinates become pixel positions and the attribute table is dropped entirely. That is fine for illustration and no use as data, so keep the FGB original if anything downstream needs to query or reproject the features.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • 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.

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’!
