Compression in SQLite database .Net C#

Can BLOB (or any other data) be compressed (on the fly) into an SQLite3 database? I'm using System.Data.SQLite in C# targeting .net 3.5.

In my search I keep seeing connection strings like so... "datasource=base.db;version=3;compress=true;"

But I can find no information about compress=true, I've added it to my connection string for testing and added file as BLOB data but there appears to be no compression, I have tested with for example a large text file, so not an already compressed image or other file.
