1 KB might be a realistic size for a low fidelity background or thumbnail, but 0.01 bytes/pixel or 0.06 bytes/pixel isn't a reasonable compression target. In other words, when making a thumbnail you should probably be downsampling the input rather than just feeding a 320x203 image into your compressor and turning down the quality setting until it fits under 1 KB.
