In general a 'PNG' image has better quality than 'GIF'. In a 'PNG' image all the pixels that the program generated are still present, exactly as they were generated. In a 'GIF' image, however, pixels may have been altered in order to accommodate a smaller file size.

 I think you're thinking of JPEG. PNG and GIF both use lossless compression, however GIF only supports 8-bit colour and 1-bit transparency. For images with no more than 256 distinct colours, PNG and GIF will probably give identical results.
 
thank you...  so it seems the GIF file is smaller but
               can show fewer  colors.
