Is it possible to compress a bak file created via maintenance plan?

Hi everyone, not a sql guru but know enough to backup and restore db files :)

I was wondering if there's a native way for sql to compress a file after creating bak file using the maintenance plan?  The way I envision is like when you manually rar or zip a back up file to shrink its size.

and if possible, does it affect how files are restored?  additional steps to uncompress these files?

Using SQL Server 2005.

thanks
