Technical note

GTIFF to AVIF: what carries over and what does not

GTIFF 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 GTIFF original if the data still has to go back into a GIS. GTIFF carries 16 bits per channel and AVIF carries 12, so tonal steps get coarser during conversion. It shows up first in smooth gradients such as skies. If the result will be edited further, move to a 12-bit format only at the very end.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see GTIFF 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.

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’!

FAQ

GTIFF to AVIF Conversion

What are GTIFF files?

GeoTIFF (.gtiff) is a georeferenced image format used for storing raster graphics with embedded geographic metadata. Common in GIS and remote sensing, it allows precise alignment with map coordinates, making it ideal for satellite imagery, terrain models, and aerial photography. GeoTIFF files are widely supported by mapping software and can be converted or edited without losing their spatial reference.

What are AVIF files?

AVIF is a new image format launched at the end of 2020. AV1 Image File Format was developed by the Alliance for Open Media in collaboration with Netflix, Google and Cisco. This format was created to be an open-sourced and royalty-free image format with a super-compression efficiency. Multiple graphics compression tests show that the .avif format outperforms the JPEG, PNG and WebP image formats for its image quality to compressed file size ratio.
