I prefer to change the icon background from white color to transparent color:

Image as it should look like

Do I need a special tool?

Personally, I use GIMP for all my graphics editing needs. It makes it trivial to make a png with transparency. If you do a lot of graphics, or even just playing around it is worth the download. Also, it's free.

Use the right tool for the job instead.

I'm sure you can find something useful here OSX Icon Editor Pack!

On windows I always recommend the free and awsome IcoFX – Nifle Jun 9 '10 at 10:12
