Do you know when to use PNG?
  v2.0 Posted at 13/10/2015 11:20 AM by Rebecca Liu

PNG is an alternative to JPG, heavily endorsed by some circles, mainly because of its open source and non-commercial nature.

PNG boasts:

  • Alpha blending (24 bit transparency map support)
  • Unlimited and limited color palettes. This makes it a good alternative to BMP.
  • Multiple CRCs so that file integrity can be checked without viewing

However, it has rather poor file compression and should be used sparingly.​
