I know of two options: The proprietary
https://sqlite.org/zipvfs/doc/trunk/www/readme.wiki and this extension that
you have to call on strings yourself:
https://github.com/siara-cc/Shox96_Sqlite_UDF

Furthermore, some filesystems allow transparent compression, like ntfs,
bcachefs, zfs and btrfs. I have a 13GB DB that takes up 850MB on btrfs.

Wout.
