It would be great to have a quiet mode available, especially when running pmtiles as part of a CI/CD pipeline. Converting mbtiles to pmtiles in our pipeline currently produces ~4,000 lines of progress bar logs. This doesn't add anything of value in this context, and it would be helpful to have a way to turn that off.

This would a good addition. I'd prefer keeping progress the default and adding --quiet instead of making quiet the default and adding --progress. What program is earlier in your pipeline that creates MBTiles?

[ebbishop]

Agreed, it makes sense to have --quiet as an opt-in feature.

We're using tippecanoe to build mbtiles from a PostGIS db, then converting to pmtiles.

If you are using the maintained version of tippecanoe https://github.com/felt/tippecanoe you can generate PMTiles directly and don't need to use go-pmtiles at all.
