No particular format inheritly features anti-aliasing, but if you've got Gimp, it's not hard to anti-alias something.
First, provide the graphic at double the size you want it, or tripple, depending on what AA quality you want.
Then load Gimp. Open the file. Hit the right mouse button on it to get a menu, then go
image > scale
Scale it to exactly the size you originally wanted. So if you wanted a 500x500 file, and trippled it to 1500x1500, scale it down to 500x500. And it'll come out antialiased!
What happens is this; Each final pixel has the data of 9 pixels if you trippled, or 4 if you doubled. So it comes out looking much higher quality.
The 3Dfx Voodoo5 was the first consumer-class graphics card to do this in real time for games. They used the term FSAA, or full-scene anti-aliasing, or supersampling. This feature is standard on most modern cards, and on the Microsoft X-Box. The X-Box was the first major system to have full-scene antialiasing, though the Nintendo 64 had standard antialiasing capability all the way back in '95, which even the Playstation2 doesn't have.
