From the paperclip wiki, there's an option for quality:

class User < ActiveRecord::Base
  has_attached_file :photo,
                    :styles => {
                      :small => {
                        :geometry => '38x38#',
                        :quality => 40,
                        :format => 'JPG'
                      },
                      :medium => {
                        :geometry => '92x92#',
                        :quality => 50
                      }
end
