If you are familiar with javascript file, you can use BananaScript to compres your javascript file (must be a .js file and should be at least 4kB in size).
I have converted iTheme Wordpress Theme to be a Blogger Template with drag&drop sidebar supported. But, the javascript file is big enough. BananaScript converted it from 20KB to 8KB (40%). I tried to open the compressed file but i couldn’t see javascript code! So, i think we can also use this tool to hide our javascript code. Amazing, isn’t it?
