And you can reduce size by 
3. adjusting levels
and/or by 
4. reduceing number of colours used.

By the way none of these ways is lossless. And you could use say jpg for 
smaller size. Or gif.

1. picture>mode>indexed
2. file>save as...><choose where to save to>>Compresion level 1...9
9th level has best compression. You can choose some other options there too.
4. Layer>colors>color decrease (or something like that cause i use Gimp in my 
native language)
