I have a database in Azure SQL. It is 50 GB in size. I made changes to many of its columns, changing nvar to var, deleting rows, but the size remains about the same. I Exported it to a backpac and imported the backpac to a local SQL Server 2016 and the local db shows its size about 34 GB. I am thinking that Azure is not compacting the db after these changes. Is there something I could/should run for Azure to compact the db?

Isn't about compacting. Things in SQL Server aren't really deleted but marked as delete. When you run a reindex the data pages will be organized and all columns marked as deleted will be physically removed.
That's also the behavior for a Restore command.

Is there away for me to have Azure physically remove the deleted items similar to what it does on a Restore?
