I used Paintbrush drawing an icon, if it is on a colored background, it will display a white block shown as below.
I prefer to change the icon background from white color to transparent color:
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.

You can actually do that using Paintbrush (Mac)
Select a foreground color - any color will do as our intention is to remove the background.
Next, drag the opacity slider from 100% to 0%. You should see your selected color turn into a grayish tone.
Now click the fill icon and click anywhere in the background.
You should see the background is now transparent.
had to fill multiple times - no shadows. still more helpful though – noɥʇʎԀʎzɐɹƆ – 2016-08-15T15:00:09.507

No installation needed - use Preview.
This is a late answer, but this is much simpler than any of the other answers. For the googlers!
Thanks. But I am useing mac os x 10.5.8, there is no version of GIMP for it. – user36089 – 2010-06-09T11:42:48.207
