About 8-bit alpha


Upload a 24-bit PNG with alpha transparency and get back an 8-bit PNG also with alpha transparency.

What 'n' why?

PNGs, alpha transparency and small file sizes are all good. After reading this article, I was inspired to squish all three of them together into a nice, friendly web service. Photoshop can't make 8-bit + alpha PNGs and sometimes you just don't want to open (or don't have) Fireworks so this site fills the gap.
