which format of png should I use?

Question

Which format of PNG should I use PNG 8 or PNG 24? Which one is better for a website. I am confused about these. What is main different between PNG 8 and PNG 2?

Answer 1

Png-24. Png-24 has alpha transparency (where Png-8 only has on/off transparency).

Png-8 is indexed. Png-24 is loss-less.

Png-24 is better in almost every way.
