ToAce

When converting bmp files to ace format, is ToAce supposed to be making the files larger in file size?
For instance: One bmp I use is 769 KB. After converting to ace it is 1.33 MB.
When I use ToAce I select the RGBA 32 bit (V2 only) option then just hit 'Save'. Is this the right way to do it?
I checked the docs and the Wiki and couldn't find anything about using ToAce.
