What browsers support PNG? and is it as good as the hype says it is?

Does anyone use PNG or are we stuck using lossy formats?

What browsers support PNG?

Hi,

I did a quick search and this one is what I found
here [libpng.org].

And who knew there were so many PNG utilities [libpng.org] available?

I'm thinking that as long as you stick to using PNG more like you would a gif, with binary transparency instead of the cool alpha transparency that PNG supports but many browsers still do not, you're pretty well safe.

I suppose I really ought to download one of the Mac PNG apps listed on the libpng.org site, and give it a try...

Besides the alpha channel support what is the advantage of PNG?

As compared to gif: Smaller file sizes possible, wider range of color supported, no messy patent/licensing issues [burnallgifs.org]...

I am a little behind on PNG. Can you make animations?

There is a related format called MNG for animation... I don't really know anything about it though.

[ligpng.org...] seems to be the central repository of info on all things PNG/MNG related... Here [libpng.org] is their page of applications that support the MNG format.

Advantages of PNG (portable network graphic):

-lossless compression scheme
-supports 8-bit indexed color, 16-bit greyscale, and 24-bit color.
-smaller file size than GIF in most cases
-variable transparency levels
