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.
Sorry, you are right. I never use GIF anymore, so indeed I read JPG instead.
