I have a GeoPackage file with a single raster layer and a total size of 0.5 GB that I want to convert to a GeoTIFF file. I imported the original .gpkg in QGIS and exported the one layer as a GeoTIFF, resulting in a file size of almost 30 GB (!!)
This seems quite weird to me. Can anyone explain why the .tif file is so much larger than the .gpkg? Can I reduce its size without compromising resolution and what are my other options for the file conversion?
