geopkg, default settings - 32,136K bytes
geopkg, manually setting TILE_FORMAT = PNG - 80,572K bytes
gtiff, default no compression - 114,287K bytes
gtiff, high compression (DEFLATE, predictor = 2) - 86,816K bytes
The default is still lossy as expected as the issue has not been resolved, but it is possible to override the defaults by providing the TILE_FORMAT = PNG options.

Hi,

I would not store raster in a geopackage unless it’s just a pretty picture. The default compression for that format is not lossless. I would just save as a .tiff.If I use Properties->Export and export to a geopkg and add TILE_FORMAT to PNG, do I get a lossless export?
(I saw this option in issue 40425 that you submitted back in 12/20.)
